<human>: Can you succinctly summarize the text in 1-3 sentences?

This was about three years ago. A bunch of my friends were riding down to a park outside of town. I didn't have a bike, so I borrowed my friend's. He neglected to tell me that the brakes didn't work. Anyway, the park was in a river valley and we had to travel down a relatively steep hill to get there. I started down, unaware that my brakes wouldn't work. I freaked out, lost control, and went headfirst down the hill over the handlebars. I landed in the middle of the road, and crawled off to the side. One of my friends called his dad, who took me home. At this point, I noticed a bruise on my hip that had swollen to the size of a tennis ball. When I got home (all the way across town), the ambulance was called, and I was taken to the hospital. There, they noticed I had been impaled and I was Life-Flighted to the Cleveland Clinic. They cleaned my wounds, whatnot. We figured out that the bike handle had hit me in the hip, which caused the hip bruise, and the brake handle had impaled my groin. It was about 1.5 cm from my junk. I got lucky, as my junk was unharmed and I had no serious internal injuries.
<bot>: Borrowed a bike, broken brakes, drove down hill, impaled groin, almost lost my junk (impaled 1.5 cm away).
