How much will GGG's age play a factor?

[boliodogs]

All boxers decline with age and the decline usually starts about when they hit 30 years old. It varies from boxer to boxer but it's very unlikely GGG is as fast, strong and sharp as he was 5 years ago even though he trains hard and takes care of himself. Canelo has just turned 27 years old. He is in his prime and as strong and fast as he ever will be with 50 pro fights worth of experience. Canelo has a solid edge as far as age goes. I still think GGG will win.

35 isnt old anymore in sports with modern nutrition and less fights and less wear and tear. Even tennis players are having longer careers and they have grand slams, tournaments and wimbledon all in 9 months.
