There is one very
important point the
fellow noders have missed. Runner's high is not only about the chemicals released in a body. Runner's high is no doubt boosted when you finish a race or a training by the good feeling and
self-respect. Running doesn't have that kind of
social stigma as, say,
marijuana or other
substances have. Even the police thinks
it's okay to run. A post-race
euphoric state is really
well-deserved because you have done good job and whereas
smoking pot spoils your lungs, running is an investment on the health. I think my runner friend put it right when he said that
you always have to pay a price to enjoy something definitely. The
exhaustion caused by running is the price but the award is twice as great.
