I don't have any large scars on me, but I do have a few.
I have one on my left thumb from a modeling knife. Don't cut towards you, it can land you in A&E.
I have a small one on the back of my right hand, but I can't remember where I got that.
I have one on the top of my head somewhere from when my brother threw a brio railway tunnel (basicly a foot long piece of wood) at me when we were both young.
I also have a surgical scar on my groin, but that was from when I was very young so I don't remember what the surgery was for.
I've also had quite a few cuts, scrapes and bruises from rugby, but no scars as of yet from that front.
