I can't do anything that will "significantly raise my heart rate" for another month.
I was in a motocross accident 3 weeks ago.
Crashed on a 110ft triple, and then got landed on. I was unconscious for over 4 minutes.
4 completely broken ribs, 3 fractured vertebrae, bruised liver, lacerated kidney and a 1cm hole in my lung that's still about 5-6mm wide.
I was in ICU for 24 hours and the hospital for 3 days.
The guy in the ambulance was telling the driver to go faster and was ready to put a chest tube in and start AR because he said my lung was collapsed and he thought I was gonna be in serious trouble. While I'm laying strapped in right next to him. Scared the shit outa me.
