By the sweat of your brow

J.'s mom and I were admiring J.'s legs the other day. She said, "If I had pretty legs like J.'s, I'd wear skirts more often."

I agreed, then said, "Would you be willing to put in the amount of time that J. does on his bike to get pretty legs?"*

We both agreed it'd be quite nice to just wake up one day to find that our legs had transformed overnight.

*I estimate that J. puts in, on average, 10-15 hours a week on his bike.
