When I hit 30, I indeed felt like I aged rapidly and could no longer pull all nighters. Life happened and I changed my job from IT to manufacturing. I was no longer sitting around on my ass all day, but actually working my body.
Few years in, I feel younger than I did at 30 and have zero issues gaming all night.
All I can suggest is do resistance training (top tier activities are running, swimming and dancing. Pretty much anything that builds cardio without excessively building mass).
