wearing loose, thick layers is better for keeping warm than wearing many thinner layers that hug the body.
check your engine oil level regularly, if you drive. not much worse is for your car than a seized engine from lack of lubrication, aside from maybe a broken timing belt on an interference engine. but you can't really check those as easily.
fingerless gloves are a gift from god.
always check the best before date when shopping in clearance sections at the supermarket. i recently discovered a bottle of fish liver oil supplements that expired over two years ago. granted, i don't think that's the kind of thing that is especially toxic when "expired", but it's safe to assume that if they let stuff go that bad for that long, other, more perishable items have fallen through the cracks as well.
if you don't mind the altered taste, you can lessen your sugar intake a bit by diluting fruit juice with water. that's what i do.
