I'm not sure I can do more than scratch the surface, but let's see....
Can't do spring-ups (the thing where you lie on your back and then kick your feet out and wind up standing)
Not very good abdominal definition
Have a mental block against jumping through windows sideways
Hair not thick and full enough
Spend too much time working on things that seem cool but really don't make much difference
Put off doing too many things that will make a difference
Collect too much junk
Really should dust more frequently
