I've got a few. One on my ear from where I hit my head on a table after my sister accidentally tripped me (I think I was 5 at the time), one on the back of my right index finger from where I brushed against the bulb of my desk lamp as a kid, three small ones on my abdomen from when my appendix got taken out, one on my arm from when I fell off my bicycle, a bunch of horizontal marks on my back that I think are stretch marks (no clue how I got those, I've been thin my whole life so it's not from fat), and I'm missing the tips of two fingers; I took off a chunk of my left middle finger using a table saw a while back, and more recently I cut off a small piece of my left index finger with an X-Acto knife.
I'm pretty clumsy, lol.
