Re: OT: How fast can people run, how high can they jump, how hard can they think?
btw, it is impossible to 'Think Hard'. the thought process is cerebral. It has no physical form. You can however 'intensify', 'focus' and 'clairify' thoughts.
As to how high a person can jump,.. well, anyone can jump off a high building
and Lastly, if you run down an almost vertical surface, you could potentially reach terminal velocity.
