I think this is good too. Many people seem to eat until they feel it -
with that particular time steadily increasing with the slow expansion
of the stomach. Generally, you're not supposed to be aware of your
body parts: aware of your eyes by seeing spots or hearing your ears
as they ring or having muscles that are sore, for example, are not desired,
so why would you want to eat to the point when you actually feel your stomach?
Drinking a good amount of water is a smart idea: good for the skin, digestion,
and just as a general restorative method - especially as you get older.
