EXTRMEME DAVE - I can relate - I had a serious spill about 5 years ago. OTB - Face plant at about 25mph at the bottom of a short decent. It was caused by me riding a frame that was too tall, too fast and lost control and couldn't pull back enough to get the front wheel up over a small log. My weight was already too far forward.. One of the biggest "thumps" I ever took and I've taken many.
I think I was knocked out for a little while, broke the helmet... By myself in the woods right before dusk.. I managed to "dazed and confused" my way home (approx 2 miles). I get home and my wife immediately took me to the hospital. At around 2am, I realized what was going on and what happened (before that was in a dream state, repeating myself over and over again) while they were x-raying my shoulder and ribs. Turned out - Concussion, bruised ribs , and amnesia. I couldn't really remember what happened so they kept me in the hospital for 3 days monitoring me to see if I had a heart attack.
Lets just say laying in the hospital for that time really messes with your head. While in bed, I was bothering my brother to find me a DH bike so that wouldn't happen again + at the time, I was married with two kids and my wife was worried that she almost lost her husband and our kids would be fatherless. That can really change your perspective on things.
Long story short, last year I finally got back onto a bike and let me tell you, I was grabbing a whole lotta brake going down hills.
I was also that guy that used to go after stuff most wouldn't. Dude, I can relate with you! I'm a BMX'er / Motocrosser at heart and if i'm not flying through the woods, it's no fun.
Luckily, I'm finally getting my inner beast back and am attacking downhills with more precision than ever.
You wanna know why? Because the last big fall didn't kill, it taught me to ride with more precision. it may sound silly but it's true - if it don't kill ya, it makes you stronger. Take it from someone who hated life without a bike, keep at it, keep going and if it didn't kill you, I hope you learned from it.
One of the coolest things happening to me right now is my kids think I'm the coolest dad because I race bikes! If I gave it up, I'd be your typical out of shape slouch proud of his lawn hating life.
Cheers!
