Time Machine Journey

If I could go on a time travel trip I would back to when I was riding my bike down a steep hill.I was only 8 years old. I didn't realize how fast I was going and I didn't have my hands on the brakes. I saw a rock and I thought my bike would go right over it, I was wrong I completely wiped out and scraped my entire leg. I would have gone back in time to warn myself about the rock and avoid it. It would have prevented a lot of pain.
