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.
