yeah exactly. he could have won all of those fights, especially as his body wasnt ruined from facing ggg, but after that he never had a chance against spence, although spence would have beaten him regardless.
I do a lot of cycling, if you want to take it easy you can do (depending on gear range) and it's low impact anyway compared to running etc. I would say he needs to watch the hard plastic edges of his sunglasses against his eye sockets though.
He needs to be particularly careful with eye drops to ensure his eyes don't pop out 6 inches in front of his nose.
