yeah probably cause you don't push it. Just wait. You'd better be gettin echo's every damn year and have an angiogram almost with the same frequency. Knowing the shit you likely stuff down your piehole cause "I needs to bulk up", you've probably got some sort of blockage going on. Difference between you and me is that when i'm 60 i will still be doing wkts that you would have struggled with in your prime. Well actually two differences, you long past your prime...i haven't even begun.
