Reading this thread makes me realize that, for age 48, I am remarkably unscarred.
I have a tiny one on my chin, where I cracked it open and needed stitches (twice!) at the age of 5 or 6.
Right knee...vertical scar about an inch long...getting it pinned and dragged along a fence by a horse that preferred not to cooperate.
And it's not a scar, but I have an extremely annoying ganglian cyst on my left wrist...looks like a lump under the skin (ick) from over-stressing the joint when I renovated my office. That one will be going when I can psych myself up enough to do it... (fraidy cat here)
That's it.
As far as scars on other people...I look at them the same way I do wrinkles or grey hair...just a part of who they are, and part of what we accumulate as we live.
