How Old Is Ox King?

[Let's Go Fearless!]

I just watched some clips on YouTube when Ox King mentioned that he and Grandpa Gohan were training partners as Roshi's disciples so it got me thinking that how old is Ox King then?

There's no official date for Gyumao's age, but we do know from the Daizenshuu timeline that Son Gohan Sr. was born in Age 658. Assuming Gyumao is of similar age to him, he'd be up to 91 in his first appearance and 126 by the End of Z.

So Chi Chi was born when he was already that old? Interesting...
