It's amazing the number that don't know those tips, and all those tips can be extended to pretty much everything... keeping on top of car maintenance, keeping that padlock oiled, cleaning the dishwasher periodically, drying whites in the sun because sunlight bleaches them, sharpening knives, pruning plants so they don't grow too big and crack the foundations of your house when they pull too much water out the ground, fixing roof tiles to keep integrity of the roof. Cleaning and maintenance... clean eating and fitness... almost like there's some sort of connection...
