it is not that straightforward
if nasser was undergoing dialysis for sometime then some of his buddies here knew about it, but kept the pretense that the guy was doing great- with fresh pics, meeting in egypt, -just until a few days the guy keeled over.
that doesn't look good on them
nasser trained with me once and did some cardio and he was training constantly during his stay with another guy who lives close to his house.. i saw him only 2 times, each time we were spending together more than 7 hours and we were walking a lot and while eating he was eating all kinds of food.. he looked good and younger after losing weight.. and the man didnt tell me anything bad about his health..
we were supposed to train together again and i was calling to confirm the day to be answered by his dad with the sad news..
ya i asked him "what happened.. did he have any problems".. the man said it was a sudden death in his sleep.. and when i visited him later i told him that rumors on the net were talking about fatal kidney problems,.. he said "nasser had a problem in his kidney but was not threatening his life and couldnt be the reason,.. especially till the last moment he was very normal talking and joking with them".. so if you were in my place,.. you were going to continue and ask nasser's devastated parents "hey come on guys,.. tell me more details,.. sure you have more to say,.. i am very curios to know more details about the death of your son"

i dont know how you deal with ppl in a situation like this but i am sure you lack the least amount of politeness and common sense..
