"How much time is left?" If I had five cents every time I heard someone say that, I'd be swimming in a pool of nickels (I'm probably better off, that sounds painful!). The fact of the matter is that we have tons of timers (ovens, microwaves, phones, etc.), but for some reason we never seem to use them! So for those who want to keep time while cooking or see how many push-ups they can do in a minute (currently I can do 35, but I'm working on it!), then give them a custom countdown timer so they'll keep you in mind as they're more mindful of time!
