genes are everything... i binge drink on the weekends my doc told me he was scared of my blood work before i did it... got it in and it was PERFECT. he made a comment to me that i must have super human genes...
You probably do - possibly overall, or possibly in certain specific ways. At 36, I am still shooting loads like Peter North was in 1993 [when he was 36], which is a minimal to zero decline from my teenage years. My sperm count was over 1.1 billion as of March 2017. Every year, I expect that to drop, and every year - it stays the same.
With that said, at 36, I also realize I should not take for granted the areas where I have good genes. I do not wish to ruin my body. I'm lucky. I'm very, very lucky. And I want to maintain this quality of life for as long as possible.
