How long does each coin flip take, and how soon can I repeat the game?  Does each flip takes an equal and finite amount of time?  Do subsequent flips take half as much time?  Can I play Graham&#x27;s number of games in an hour?  An countable infinite number of games in an hour?  If we&#x27;re wondering about &quot;most people&quot; they might be sub-consciously taking the time factor into account.
