Things it took me till age 61 to learn

I can't believe it took me all this time to learn (amongst other things):

1. When shaving, you can tap the narrow end of the razor against
the sink to help clear it of shaved hairs, thus giving a better shave and prolonging the life of the
razor. I used to just run it under the tap thinking that cleared most of it, but have now found it came
nowhere near clearing as much.

2. When using a pepper grinder one needs to turn the top in only
one direction ever, otherwise (ie by turning the top back and forth) the blade (for lack of the proper
term) gets dulled and it's virtually useless.

Amazing.
