After watching the rematch of Donaire vs Naoya Inoue, you can see that Donaire no longer has his main advantage - speed and simply does not have time to react to enemy attacks, age still affects him, and by moving to a heavier weight category, he also risks his health
I wasn't expecting that from Donaire because he was aggressive during his younger days fights. I think his age really affected his performance and stamina. Maybe that's the reason why he wants to rest for a while. We can't deny that Inoue has fast hands and strategic punches, he was a big challenge for Donaire.
