Tweetyeah man that is crazy. i have had some chest pain issues in the past and i am in my early 30s. i went in and got checked out and they told me that mine was due to indigestion and really bad gas. i was like for real even with it shooting down my arms and hurting to take a deep breath. docs said yep you are good you just got some bad guts.
on another note, one of the old guys that trained at my gym dropped dead from a massive heart attack in his early 60s. the dude was in crazy cardio shape. he ran marathons spin classes 2x ed, ran the whole 9 yards. he just feel off the spin bike one day and it was over.
the body is such a crazy thing
