Why am I always hurting myself?

Seriously. My wife tells me she hears me say “ouch” about 5 times a day. Today, someone at work told me they hear me me say “ouch” all the time. I bump into things, slam my fingers in my desk drawer, hit my elbow on my desk, slam my arm into the door jamb when I walk by, come up with random bruises, etc. I already wear glasses, and I get my eyes checked once a year. What else could it be? I haven’t always been like this. At least I don’t remember always being so clumsy.
