Holy shit dude, but you know what that is true. That deep-vein-thrombosis (DVT) is real and it does happen to people who do not exercise and just sit down for hours and hours.
I actually have symptoms of DVT according to my DR at the VA Hospital. Being a smoker and no exercising fucked me up big time. I am looking to find out if I have diabetes and DVT, I am just waiting on the appointment letter to get here.
Shit is real guys, don't take this as a joke!
