[SPAD-1949]

The Human Body consists widely of fluids in Narrow containments.
It takes a small ammount of time to allow the blood widen the vessels and follow inertia.
Therefore it is possible for martial arts fighters to break concrete slabs wthout beeing hurt and this is also the reason why red bull air racers are restricted to 10 or 11g reached at the top of the turn loop because the aircraft could break, while the pilots withstand this forces induced for a very short time with ease. Exeeding 11g leads to disqualification.
