signs of fighters who are getting old

[THE THIRD MAN]

The ability to avoid being hit. Jones jr was a master defensive fighter,then he got hit and hit regularly. It's your ability to land your power shots regularly and avoid beng hit in return that is the key, Mosley has lost both. He still packs a punch, but no longer has the speed in which to deliver it quickly and accurately enough to end a fight like he used too.
Injuires over the age of 30 can be a huge factor, Tszyu was never the same after shoulder surgery at age 34 and being out of the ring from January 03 till November 04. Fighting just 3 rounds in 2 and a half years in your mid 30's and then facing a peak Hatton saw Tszyu get old in one fight. Ali was officially old after the Thriller in Manilla, sadly he went on for another 5 years!!

A fighter's getting old when he and his kid are on the same card.
