Heck even electrical outlets start to fail after 50 or so insertions -
ever notice how a socket you use for the coffee pot feels looser and the
plug seems warmer than it did when they were new?

In my limited experience (sample size of 1) that's not true. I have a
toaster that I only plug in when I use it. Which is 1-2 times a week,
for 20(?) years: 1000 or 2000 times & no noticeable looseness.
