Thanks to everyone for the input on splitting nails.  There's lots of info 
there to mull over and try to put to use.  I will respond to a couple of 
things. 
 First, I did the gelatin/orange juice/colloidal mineral thing for years, ala 
Dead Doctors Don't Lie.  I think it's a wise thing to do, but didn't notice 
any improvement in my nails which have been poor quality all of my life -- and 
worse lately.  Also, I do take supplements on a daily basis which consist of, 
among others, Calcium, Vit. B, Vit. E and Beta Carotene -- maybe I'm not 
taking enough?  Additionally, I no longer own a gall bladder, but I do own a 
liver. 
 And it's probably abused, as I do enjoy my evening cocktail.  Oh -- and a 
response to Faith -- the worst thing that I put my hands into is Dawn 
dishwashing detergent.  The other things I have to take some time to absorb.  
You'all 
are great -- thanks.      MA
