I have a friend who collects and restores old calculators from the '70s. He noticed that resistors deteriorate when not used, but can be preserved or restored by periodic use. He uses calculators in his work, so his practice has been to take to work and use a different calculator from his collection each week. He says they last a lot better with periodic use.
