Floors though. It's weird how important they are in our life timeline. Whether finding gold shag in old photos or finding a random scrap of linoleum tossed into a ditch, we point at it and say "HOLY COW I haven't seen that floor since I was THREE." I'm sure my decade (probably life?) of work in a greasy kitchen will have the same effect. I will probably never forget the square, brown tiles I walk across almost every single day. Especially the ones that were poorly replaced and thus not only are already cracked but continually annoy me as I try to drag 300 pounds of meat around them. That's all there will be in my visual timeline - wall to wall brown tiles, often covered in oil, sometimes covered in ants, occasionally covered in someone's blood.
