Why do people run marathon races? It costs money
and is painful. I have done that a few times. I think it is something I can be proud of towards myself.
Why do people climb Mount Everest? Because it is there.
Looking up to people who have done similar feats, and do a similar thing or even better oneself.
Why do people have leasure boats? Costly, little space, uncomfortable. Because it is fun.
Often I get the impression that people believe that there feelings are correct in a scentific meaning of the word correct. Meaning that people who like other things are wrong or odd.
In part that is rethoric (the art of talking well). It is more convincing to say "Sailing nonstop is stupid", compared to saying "In my opinion, sailing nonstop is stupid".
