Standardization makes life easier, but why these numbers for these things?
88 keys on a piano: why not 90 or 100?
6 strings on a guitar: sure there are 12 string guitars too, but why not 7 or 8 string guitars?
9 players on a baseball team: what’s up with that short stop?
11 players on a soccer team: why not 10, 12, or 15?
4/5 forward gears in a regular car: I’d like 6, and maybe 2 reverse gears too.
2 plug-ins on electrical wall outlets: I always wish there were more. 4 would be nice.
28 days in February: can’t the other months share a few days to even things out?
and
Scoring in tennis: love, 15, 30, 40, deuce, ad in, ad out.
There are some traditions worth keeping, and then there is confusion and insanity.
