the cool thing about being an American is that if anything happens to my left arm that even vaguely feels heart related, the only thing i can do is just hope i don't die from it
(i doubt anything is actually wrong, my heart rate never went above 120 while i was running and my resting heart rate is normally pretty low, but still. I'd rather just... be able to see a doctor when mysterious pain arises, among other qualities the better world seems to have.)
