Tea, 5 min timer for my drip coffee vessel to mostly finish dripping, toasting poptarts, toaster strudels, garlic bread, toast etc to perfection.. Laundry, my aquarium’s water conditioner working (takes 10 min) and probably most important, a 1 hour timer after I finish a meal while drinking soda or Coke, so I make sure my enamel isn’t soft and it’s safe to brush my teeth.
