Isn't it crazy that fitness used to refer to your ability to not get tired while doing normal activities?
Wow! I had no idea. Do you know when the current day meaning of fitness originated?
I think that it was in the 1950's, after World War II.
Neat! There has been a huge increase in fitness program popularity in the pst couple decades.
Yes there has.  Likely due to the correlation of fitness with attractiveness.
