According to
the results of calculation, the longevity caused by exercise seems not
to have a relation to
Relativity Theory.
Actually before I calculated in practice, I thought
that there was the effect of at least one second, but the
speed of light is faster than I expected. The astronauts can
verify the effect with their watches if they
have been in the space station for 100 years. If the space ship
is for traveling in space, the effect becomes
more obvious, like the movie,"PLANET OF THE APES".
