its the same as jogging around the block
when you jog around the block your body heats up
and when it cools down your body stores more oxygen
and when you do it everyday your body stores more
oxygen and you learn better
a needle to change body temperature heats and cools
the body to store more oxygen
Why not recommend jogging or brisk walking
followed by ice packs + cold drinks, then?
Instead of this needle thing.
