I was going to ride my bike with my friend and right before we were about to leave I said “Do you think I should wear a helmet?” And I forgot what he said but I just had the urge to wear it. I decided that I should and we left. While heading down a big hill I was going really fast and slammed the breaks on my bike and since only my front ones worked, I front flipped and my head went went sliding on the pavement really hard for a good 5 seconds… I was tangled with the bike the it was on top of me and I was a little shocked in the moment. I quickly got up and started to move parts of my body back and forth to see if anything was broken or sprained. I ended up getting a sprained wrist but if I recall, I didn’t get any cuts or anything. Thank God I had that helmet on because if I didn’t, my skull would’ve been cracked open and since I was kinda far from my house, I have no idea what would’ve happened.
