Q1 wow brilliant there is going to be a demo by Mr G
Q2 One more demo
Q3 3rsd demo of invisible danger
Q5 This is well already demonstrated by the author Q & A in many quora
reproductions; many of us are post graduates but even among the equals,
some are not as they are yet to cross the pre=KGSs. There is a difference
in thinking and is it an evolutionary cult?. Hence perhaps descarte said I
THINK THEREFORE I EXIST ( WHICH MEANS THE EXISTENCE OF THE SPECIES ALL ONLY
BECAUSE OF THE THINKING) AND KARL mARX DEATH WAS WRITTEN AS, " THE THINKING
IS STOPPED FINALLY". ( MEANING NO MORE BLABBERINGS?)
Q6 At this age all the oldies shall have regret about this but the
repetitive pleadings , issue by issue , may not get in any solution. The
system in 95% of the species gets slowed down because of the slowing down
of the nervous system , resulting in a slow process. Also the digestive
system metabolically shrinks down to a level below normal, hence only what
once one was consuming , is not being done now. Fiber eating or even
laxative consumption may not get the required, demanding results in the
bowel movements. There are people above the 80s who say that they go for
motion only after every 3 days. Exercises and food are for normal persons
hence only I write, do not take much into your head where the Q is getting
shortened. Broaden the vision and maintain the equanimity. Eat for
sustenance; leave greed; and live life along with nature.
Q9 Gossip answers; there is nothing wrong if we switch on motors 10 times
or 100 times a day; the energy efficiency is higher if 100% is used than
many a times operation that exerts only decreased efficiency several times.
Electricity charges might vary causing a bit higher than the one time shot
consumption. Apart from all these wear and tear would increase whenever
from rest to reaction had to occur. The Amount of Energy in Kilowatt-Hours

Q10 Leave aside the balcony window, bottom of the ship etc; ship
travel is not that easy; sleeping in the ship in the best suit for many is
next to impossible due to the swaying of the ship according to the
pressures of the waves of the sea. Even to walk on the deck one needs
practice. a few are gifted with such talents. So balcony etc are another.
