HI Jonathan,

hmm... this sounds suspiciously like you're hoping for some easy answers to an essay question?!?!?

if that's the case, i'd encourage you to come up with your own theories and think of the background as to why the athletes mentioned might have collapsed in the first place and how you would assess them from that view point. There are some very important differences but i'm not going to spoil the fun for you to do your own research.

Best of luck,
