Will exercises like crazy age me quicker?

[WarVeteranO01]

Some anaerobic exercises I do like sprinting at my maximum possible speed as long as possible my legs can endure, as if my heart is about to explode out of my chest. Or long sparring sessions at maximum speed till I drop. I've been worrying that these exercises that make my whole shirt wet could be an age accelerator. Can this be true?

Your heart is a muscle bro, the more working out "cardio" (especially in intervals) the stronger itll get. Of course like anything trust your body and know your limits. Hydrate and remember to breath if you feel nauseous or dizzy, take a break if you have to. Also remember its sparring so its practice, if you are killing yourself your throwing skill out the window.
