Hope he is much better now!
Health becomes a big issue when you get unwell. Strangely enough, even overeating and indigestion can also cause health alarm (at any age, these days) .
Only the closest family members can really feel and understand it's implications. Therefore it's very important to keep a close watch, always or as best as one can, to avoid such situations.
Ironically, you cannot be strict with the parents as we can be with our children, since they feel offended. Such is life.
That's very correct, we even don't have digestion power like their generation, may be something related to stress.
I believe it's more to do with compromised eating habits and usually unhealthy and non-balanced diet that we all follow to a much greater extent these days, usually and above all so called junk food becoming integral part of our lives.
Therefore it's definitely going to effect and impact our digestive system to a greater extent, causing lot more other health problems and complications later on.
Over eating and junk food is a No-No for me as well, but I too easily deviate and dilute the principles.
