I read yday on the speed awareness thread about not going higher than 3rd gear in a 30 to avoid speeding and that red roads are expensive and so only put where needed: noted both on my journey in town today.
Made me wonder what else like that others could share
My others are quite random
I read once that turning off the tap while you brush your teeth makes a big difference to water use. Since hearing that I always make a point of doing it
I am less religious about this one but to practise balancing in one leg when brushing teeth to help with balance as you get older (I am 46 so not decrepit yet)
Working as a waitress I learned to wipe wooden tables in the same direction as the grain to keep them streak free have always remembered ever since
Any more?
