Just thought I'd mention this or bring it to your attention because I've never had this happen before or given it a second thought.
Yesterday I was shooting in my backyard at a bag target and missed, the bag is sitting in front of a brick wall. Arrow hits the bricks and comes flying back right at me at ground level and hits me in the foot and am wearing flip flops. Luckily the head breaks off(Small game Thumper) and hits me in the side of the foot. No big deal small little cut but if that head stayed in tack I would have had a really nasty gash or if the arrow came back at head level it could have killed me or anyone else in the yard at the time. It happened so fast I couldn't react in time to get out of the way. I saw it coming like in slow motion. Time to move the bag or hang some carpet behind it...big eye opener for me.
