Sergio SR. won all his Mr. O's by age 28. Sergio JR. is around 33. Even in 2014 he was 30.
In the Generation Iron interview, Sergio Jr. stated that Sergio Sr. lied on his birth certificate when he defected to the USA, and was actually close to 80 when he passed away in 2012. I took that to mean that Sr. was born around 1935.
If so, that means he was 33 in 1968. Something like that.
So I suppose we would have to compare it to around then.
And it is safe to say he does not have his dad's genetics......but I do think his genetics are very good.
