I bought a piece of 1.5 inch stiff foam to try to fix a sag in a bed. It didn't work but having that thick piece of solid foam around has been a life saver.
Need something flat to put a laptop on? Throw it on the foam. Going to be doing something that requires you to be on your knees for a while? Get the foam!
It went from stupid purchase to something I'd gladly replace if it broke.
This one really shocked me, too! I got a Fitbit to monitor my heart rate because of a genetic condition, but fast forward a couple years and I'm running a mile and exercising multiple times a week.
Didn't see that coming, but a nice result!
Tbh, I hate the Fitbit though. I hate that it's owned by Google and they charge me to see my own data. I'd love to switch, but I can't find alternatives that check all the boxes from a Charge 5....
Edit: if you're looking to get a Fitbit and wanna save some money, thrift stores often have electronic sections full of em! My bf got his charge 5 for 50$ from a goodwill. Same one 100$ more in the target across the street.
