So.. had a recent health scare and basically turns out I have a really low resting heart rate (around 45 on average and into the 30's at night) -53 yr old in good shape, but not ultra-marathoner shape or anything. Previous physicals hadn't really had it show up (walking in maybe elevated it enough or something). Now it's more anxiety than anything after Iowa Heart found nothing really wrong (was admitted because apparently was dehydrated and fainted while doing a middle of the night bathroom run) and it helps to hear that this is more normal than I think to have a really low resting heart rate!
