What is Usyks limit now?

How much more can Usyk go?

His speed (and skill obviously) is an integral part of his game and given that he is pushing 40 it seems eventually he will get caught as his body slowly ages, so my question is how much more can be push?

Personally I think it's somewhere between 1-3 fights left. One fight seems the most reasonable, bank one more defence against Parker/Dubois winner and ride off into the sunset. But with the Ukraine war still ongoing and he himself saying he can push more makes you wonder how far he is going to go.

Perhaps fights against Zhang or Hygrovic.....maybe dropping down to cruiserweight one last time?

The dude is a WINNER so I wouldn't put it past him honestly but curious to know everyone's thoughts.
