DISCOVERING THE UN-NATURAL SELF

Does getting into a 747 and flying 5946 miles across the pale bule waters of Atlantic change a person drastically enough that he refuses to recognize his past? Afterall that isnt any big a deal. Many others have done that before, staying sane. Then why do some people force themselves into this often stressful artificial self?
Ofcourse Darwin said that quick adaptation is the key to evolution but that doesnt mean you imbibe whatever you see around not giving a thought about its necessity. Cows dont need claws to eat grass in the savana.Do they?

Perhaps its just that they dont have a past worth preserving....
