my heartrate is constantly about 100, and im not nervous and i dont eat crappy fast food, maybe like once a month, and i get more than enough nutrients, i do my daily workouts, and my cardio. it just seems even after im done with all my workouts and stuff, and im just sitting here, its still about 100, to be exact it was 101 in 60 seconds...... and i dont drink coffee anymore, nor do i drink energy drinks... my blood pressure seems fine, but im not sure..
