Is it just me? Or do you not talk about Health Issues ?

It's like anything else. Talking about things can be helpful and educational - morally supportive. Even just the moral support can be really important when someone is dealing with serious issues.

I think what the OP was referring to is when the subject goes beyond the realm of reasonable.... like the ppl whose meal was ruined by surgery details.

We are all different and that's what makes the world go 'round.
