Rebuilding a broken body

Well, here i am.
Its been over 2 years since i was in a gym, or had any thought of what i ate. Infact, for a year and a half, ive been VERY sedentary. Almost all of that time, i sat in front of the TV, hardly moving but to use the bathroom, or go to sleep.
Sounds like a right lazy person huh?

Well, i MAY have had an excuse. I was involved in a horrific road accident, which left me being airlifted to hospital, my wife, 5yr old son and 2 WEEK OLD baby (yes 2 weeks!) being told there may be bad news. You see my spine was smashed in two places, my neck broken, my right lower leg held on by the skin at the rear of the knee, my left ankle shattered and worse still, my head swollen to twice its original size.
Yet with excellent doctors, surgeons, and nurses, here i am. Its took a year to learn to walk again, and finally i am beginning my excersise regime.
With the help of the app, tracking what excersises i do daily, what i eat, i can keep a log and show my Physio. Plus, it helps guide me to loose the weight. Every kilo i carry in weight is multiplied to my knee and ankle every time i walk. So i have a serious incentive to loose some big pounds!
Ive had the whole knee replaced and ligaments rebuilt, the ankle has been partially built from tin cans (thats what i call it! Gotta keep a smile!)
My spine has a huge rod down its middle, with enough screws to build a shed, and whatever angel was looking after me that day prevented me from serious brain damage.
Im here, with my wife and two boys, and i WILL show them what daddy can do. Im going to do this, im going to reach my goal, and hopefully this app will help.
