Do we get our priorities right?

A friend has just bought, for over $500, the latest, most advanced, can do all vacuum-cleaner, which should make housework an effortless exercise. She uses the time and energy she now has to go to the gym and get fit.

I don’t get it at all. Doesn’t it make more sense to get the hardest to use machine for about £50. This would give her all the exercise she needs at home, while saving her the time and money she spends in the gym?
