this has got to be the most ridiculous "argument" ive ever seen.

the "logic" comes down to saying things like health, risk, and even reasoning, are meaningless. this does not help life expectancy in cultures/societies where this is the case.

let me clarify crossing the sahara for fun - on foot, across the longest span.

not to mention, if you have a huge risk of dying with an expert guide, how is that not adventure?

also - underwater cave diving and HALO jumping.

this is actually interesting >

1. risk / chance
2. "exciting or remarkable experience"
