How does a boxer know

When their life bar is 95 percent depleted........have you ever played street fighter?

 

When they realise they are too big and strong for their nearest challenger.

 

When there are no more challanges.
You have done it all.

 

Ask Roy Jones Jr...he knows all the secrets!

 

when your reflexes are gone

 

He knows it's time to hang em up when he puts on his trunks and his sacks are hanging out, or when every time he gets hit with a hard shot he feels a real need to take a dump.

 

When he goes to the dentist for a haircut

 

:good

 

This thread is a winner

 

When he runs back to 154lb to fight the weakest champion instead of backing up his boasts :think

 

Judging by how man fight past prime, most don't

 

When you let Buster Douglas beat you up.

 

They don't at least most of them don't.
