What small, everyday life tips do you have to offer?
I’ll go first. After your turn the water off in the shower but before you get out, use your hands to wipe off any standing water on your body. Maybe even give your legs a bit of a shake. This way, you won’t drip nearly as much when you get out, keeping the floor and your towel drier.
If you’re changing batteries on a device and get the used and new ones mixed up - or simply aren’t sure if they’re dead or if the issue is elsewhere - you can drop the battery on its base from about 10 cm high. If it bounces, it’s empty; if it doesn’t, it’s full. Allegedly, this doesn’t work with all types of batteries, but it probably works with the ones you’re using, which are likely Alkaline AA or AAA ones.
For anyone who's confused as to how this sorcery could work, it's due to the chemistry/physics of the battery. As batteries discharge, there is more crystal growth of the electrolyte. Crystals can store mechanical energy like a spring, while the electrolyte in solution absorbs energy. It's like dropping a water balloon vs dropping a solid rubber ball.
Get a cheap battery tester. I've pulled two batteries from a device and had one completely dead while the other still has a full charge. I keep all my good used batteries in an old clear vhs case.
