Q1           Whatare the main differences between living in the UK and living 
in the USA?

A1           Ken Saladin I know nothing about thissubject Apr 29

My guess—although Idon’t know if it’s correct—is that one of the biggest 
differences between life in the twocountries has to do with the amount of space 
available in proportion to thepopulation. 

In the U.S., Ithink the average home size and personal land area around the 
house aresignificantly larger, and Americans outside of major cities are more 
likely tohave detached houses. 

My source[1]says the average home in England and Wales is about one-third of 
the averagesized house in the United States. The average UK home is 
reportedthere as 49 m.sq., and the average US home 90 m.sq. Home in the U.S. 
also aresignificantly less expensive relative to household income.

Car ownership is another difference. The average U.K.household owned 1.21 cars 
in 2019, and 1.88 in the U.S. Outside of big cities,the U.S. has a pretty poor 
system of public transportation (buses, trains,subways). A husband and wife (or 
other couple) will usually each have their owncar, and not uncommonly their 
live-in teenage children will also have theirown.

I think Americans are accustomed to keeping a much biggerpercentage of their 
earned income than Brits, anddeciding for themselves how to spend it. Brits are 
taxed more heavily but get more prepaidgovernment services, most notably in 
healthcare.

These are muchbigger, more pervasive differences, making a bigger impact on 
people’s everydaylives and attitudes, than the gun issue flogged so far in this 
thread.

Q2           Howdoes aging affect your life?

A2           John Fenn, BDSc, Dip American Academyof Pain ManagementUpdated Wed

I turned 70 about 6months ago.I have noticed,

I hurt more by afternoon and tend to use more Advil andPanadol than before.

I forgetappointments more, and I write a lot of stuff down to remind me.I find 
filling out forms and dealingwith bureaucratic pissants to be very confusing 
and frustrating.

I awake very early, but need a nap by early afternoon.I have lost interest in 
owning things, fixing thingsand building things.

    I have lost interest in listening to peopletalk. on and on they go.    I 
abhorviolence and drama, so I no longer have a TV.

I got rid of theKombi and the 4 wheel drive, and it was a relief not to have to 
worry aboutthem or maintain them any more.

I take more pleasure in nature, birds, plants and animals.

I am heading off toFrance for 5 weeks, no agenda, no bookings, just a backpack, 
a tent and a boxof pills.

I know that I shall die at some point, but it no longerbothers me.    I 
amconcentrating on getting as much pleasure as I can out of life these days.

I worry about thestate of the earth. We boomers did mess up some stuff, but we 
built the lifeyou all lead.

I do hope I get tosee the cessation of fossil fuels, that would be neat to see. 
   I am thankful that I am an atheist. I haveexperienced hell on earth, I would 
not want to risk that again.

I finally understand myself, how I tried my best but howinsignificant I truly 
was   and I am OKwith that.

My note- I liked the answer very much since I am 78. Manythings told are very 
true. Laziness and tiredness havecome to me, and my postings to groups, I do as 
if it is a compelled duty by me.The old interest has gone, especially because 
of a member behaviour abusing inTamil and using uncultured language. 

Q3           Whatis the evidence that humans only started practicing 
agriculture a few thousandyears ago?

A3           Matt Riggsby BA Anthropology, U.C.Berkeley Mon

We don’t see positive evidence of agriculture appear untilabout 12,000 years 
ago in the Middle East andsomewhat after that elsewhere. We start to see 
archaeological remains ofdomesticated plants (the selective breeding implicit 
in the domesticationprocess makes certain detectable changes in cultivated 
species), remains oftools suitable for agriculture and processing harvests, 
remains of architecturesuitable for storing agricultural produce, and the like. 
Before that, we don’t have such evidence.

Now, there areindications of a sort of slow run up to agriculture. Hunter 
gatherers did interact with theirenvironment without going into full-blown 
agriculture. For example,it’s generally believed that late Paleolithic 
gathering techniques primedcereals for domestication, that people in the Middle 
East deliberatelydisturbed the ground in ways which would encourage the growth 
of grasses, andthat some eastern woodlands Native American groups used 
controlled burns toclear underbrush from their forests, which was useful in a 
number of ways(better sight lines for hunting, returning nutrients to the soil, 
etc.). Butthese techniques aren’t generally regarded as agriculture itself. A 
lot of native Californianssubsisted largely on acorns, for example, but there’s 
no indication that theyplanted and tended oak trees. Rather, they largely just 
enjoyed theproducts of existing oak forests.

That said, havingread the extensive comment by the OP, I need to address the 
fundamentalargument from incredulity. While it might be difficult for someone 
who knowsnothing about hunter-gatherers to imagine how they could survive in a 
temperatewinter, it is very clearly possible and more than possible. Something 
elsearchaeologists use is what’s called ethnographic analogy. If we 
findtechnologies parallel to documented, observed societies, we take that 
asplausible evidence of similar lifestyles and strategies. And there’s 
asubstantial body of documentation on living, directly observed 
hunter-gatherergroups who get along—or rather, got along; like most other 
hunter-gatherers,they’ve been wiped out—in places as far north as the Arctic 
without needingagriculture. While I don’t have the relevant research at my 
fingertips on thespecifics of their lifestyles, I can point out that the 
existence ofhunter-gatherer groups in a range stretching from what’s now Oregon 
to thenorth coat of Alaska, to say nothing of similar groups who once 
inhabitedSiberia, amply demonstrates that survival as a hunter-gatherer in the 
mostpunishing climates is not prohibitively difficult. Hunter-gatherers knew 
theirenvironment well and had strategies for surviving in it. There was 
nothingrandom or haphazard about the way they lived. Just what they ate and 
whendepends on the specifics of their environment, but they clearly could do 
justfine without deliberately cultivating food, and in the absence of 
directevidence of anything to the contrary, that appears to be what they did.

Q4           Whydon’t Indian Railways increase coaches for waiting list 
passengers? They arealso paying the same as others, but why is the demand of 
travellers notutilised by Indian railways?

A4           TruthSeeker May 8

I think (not sure) but if they add an extra 23rd coach(22 are already there) 
then additional coach would stop outside station limits.Engine cannot cross 
signal line hence engine cannotadjust either to accommodate that extra coach. 

Coach outsidestation is an additional trouble as well as risk for people as 
they cannot getdown properly specially elders. If they try to stop that train 
twice at thesame station to accommodate that extra coach it will be waste of 
time forrailways and passengers. MumbaiAhmedabad Gujarat Express halts at Dadar 
twice but it only does it for Dadardue to the crowd and due to last few coaches 
are linked to pass through fromanother coach.

Imagine a trainlike Lokshakti Exp from Mumbai to Ahmedabad halting multiple at 
all 17 stations(17x2=34times) how frustrating it can be. OR imagine trouble to 
get down fromthat extra coach which halts outside all 17 stations.

Having said this, they do increase coaches for trainslike double decker as it 
runs with only 11 coaches. So wherever possible IndianRailways does its best to 
add more people. For Example: NewSleeper Coaches have capacity of 80 passengers 
instead of 72 earlier.

My note- One more train in the direction is a goodsolution. The ex- prestigious 
Brindavan express now goeswith Non AC chair car and unreserved coaches just 
after Double decker from Chennaito Bangalore and Bangalore to Chennai, on 
account of which Double decker reservation is possible even 3 hours before the 
startingof train. 

Q5           Inlong-distance trains, how do drivers and guards ensure that all 
the railwayemployees (security, TT, drivers, etc.) have changed the shifts in 
the shiftchange railway station?

A5           Ramesh S BA degree in Economics fromMaharaj's College, University 
of Mysore. (Graduated 1982) Mon

Railway hasallocated duties to department in such a way that each of them work 
as perworking jurisdiction. Theyare responsible for duties work as per rosted 
hours. That's railway, they don't sleep when other have nice sleep.It's runsall 
24hours×365 days

Each departmentwill be functional as on shifts.

Q6           Why isliquid methane the preferred fuel in rockets instead of 
liquid hydrogen?

A6           C Stuart Hardwick. Has been known tocut open a rocket or two. Fri

Hydrogen is the most efficient possible chemical rocketfuel by weight, but is 
extremely voluminous, requiringtanks so large, they offset the efficiency of 
the fuel.Hydrogen isexpensive to procure, store, and transport in large 
cryogenic quantities.

Liquid hydrogenboils off too fast. This is a problem in the ground and also in 
space. On theground, it means waste. In space, it means tight orbital transfer 
windows orcarrying extra fuel to widen the windows, further eroding the 
efficiencyadvantage of the fuel.

Methane isalmost as weight-efficient as hydrogen and almost as clean as 
hydrogen but ismuch denser than hydrogen, and can be made even denser by 
chilling below itsliquefication temperature, something not possible with 
hydrogen. It’s muchcheaper to procure, store, and handle, and the smaller tanks 
are needed to holdit offset its lower fuel efficiency.

Q7           How dosnakes not suffocate themselves when they constrict?

A7           Alex Cooper Animal enthusiast May 4

That’s a good question, and one that had scientistsscratching their heads.

Yet these (snakes)increase oxygen consumption by almost 7 times while subduing 
their victimscompared to resting rates, and up to 17 times to digest prey a 
quarter of theirown body weight. How boaconstrictors manage to squeeze the life 
out of another animal for up to 45minutes, yet still are able to breathe, has 
been a long-standing mystery.[1]

The answer is linked to the fact thatsnakes have no diaphragm, and rely 
completely on their rib muscles to breathe.

Scientists recentlytested how constricting snakes (specifically boa 
constrictors) could stillbreathe while squeezing the life out of their prey. 
(Incidentally, they don’tkill via suffocation, they kill by cutting off the 
blood circulation, causingcirculatory arrest. This is a quicker way to kill.)

The scientists carried out the test by strapping bloodpressure cuffs to a boa 
constrictor’s body, restricting motion in certain areasto simulate the snake 
squeezing its prey. Theyimplanted electrodes in the snakes’ lungs to track 
muscle movements, and usedx-ray video to monitor how the ribs moved.

Here’s what they found:

As the researchersmoved the cuff up and down their bodies, the boasshifted 
their breathing to use the ribs that weren’t gripped by the cuff,the team 
reports today in the Journal of Experimental Biology. When the cuff was 
tightenedcloser to the snake’s tail—as might happen in some constriction 
positions—theanimal used the ribs closer to its head to suck air into the blood 
vessel-richsections at the top of the lungs.

But when the cuffwas tightened on the ribs close to the animal’s head—as might 
happen duringother constriction postures—the snake used its lower lung section 
to pull airthrough the front lungs where oxygen is absorbed like a fireplace 
bellows, theteam says.[2]
