Bicyclist hit by semi learns to walk again

So I hope this is okay to post here. Just thought I would share this story. Derek was a friend of mine back when I was 18. We dated for several months as well but have lost contact until not too long before this accident.
Honestly I believe its a miracle! He's in such good spirits now. But to seriously live after being hit by a semi.. Crazy.

Story:

MADISON (WKOW) -- A Madison man is learning to walk again after being hit by a semi while on his bike.
Derek Preston, 23, says he doesn't remember the accident itself. "I remember biking to the intersection and I remember going through the intersection on the green light, next thing I know I'm at the hospital."
Derek rode his bike to and from work every day. He was on his lunch break in August when police say a semi ran a red light and hit him. "My back tire got hit by the front cab of the semi and it sling-shotted me into the whole side of the trailer," Derek told 27 News. "My bike flew one direction. I flew 30 feet some other direction. I was in critical condition at that point."
His back fractured in three places. He had a broken femur, a broken pelvis, broken ribs, a collapsed lung and a tear in his bladder. But he was happy to be alive. His helmet prevented any head injuries. Derek says, "I wear it every day. Well, actually the day before, I forgot it and I never do that, but I was already halfway to work."
He hates to think what could have happened if the accident happened one day before.
Derek had to stay in bed for nearly 3 months. He finally stood for the first time since his accident a month ago. Since then, his trainers at oak park place have been amazed at his progress. He's relearning to walk; up and down the stairs, too. "You only get to experience walking in one life and you won't remember it, so I feel pretty proud of myself."
Derek may have some lingering health issues, but he does plan to bike again. He admits to being a little nervous. "I was a pretty lucky guy before all this but after all broken bones, I was lucky I was wearing my helmet that day. It saved my life.

wow thats amazing!
