Figure It Out

A word problem:

Yesterday, my husband went on an 80 mile bike ride. At the end, he felt great and is excited to plan a 100 mile ride.

While he was doing this, I was working at my sedentary office job. Which was unremarkable, except for an event late in the day... 

During the afternoon, I caught my foot on a cord behind my desk, did an involuntary shuffle-off-to-Buffalo through the doorway of my office, windmilled my arms while trying to prevent the (inevitable) fall, and landed in a rather inelegant heap next to one of my colleagues’ desks in a large, open space in the middle of our suite.

Question: How much longer before my husband realizes he can do better?
