Working may or may not add more gas over time but it definitely opens up the blood vessels whereas resting then contracts them, so you ongas wide open and offgas restriced. Otherwise, the real story on exertion is the damage you are doing under presusre, not the ongassing. Time and pressure will eventually take over that outcome. David Geffen wrote: > > Thanks.
