These  are great for opening letters, soda cans, reaching into tight spots, poking holes in things, opening key rings, etc. I use mine at least twice a day!

A correlary to this is to only check email a few times a day. I get about 2-300 emails a day and I need to see/take action on about 1% of them, am interested in about 5% of them.

There are many over complicated videos on how to do this but simply wipe the pan with a thin layer of Crisco. cook, wipe/scrub and don't use soap, dry with a paper towel and then coat with Crisco before you put the pan away. After a few rounds of this you will have a non stick pan. If you really burn something you can just sand it down and start again. If you cleaned it this way and are still getting a fish odor or something go ahead and use soap: it is cast iron you won't hurt it.

The head is about the size of your thumb. No power necessary and they last for a really long time. Better than electric.

For example, we have 2 cars so instead of having one key ring that weighs a pound I have duplicate house keys on each ring so I have all the keys I need whether I take one car or the other but I don't need to take bulky keys that I don't need. I have smaller sets of keys for going on bike rides or walking the dog, etc.

Assuming you like mushrooms! They last forever, they are filling and have almost zero calories. Pour boiling water on them to hydrate them and add them to soups, stir fry, steak sandwiches, etc.

I bought a 1 pound bag and I will get 2 dozen meals out of it.

Yellow headlights are usually caused by oxidation that can be sanded off. Buy some sandpaper in 400-800-1200-2000 grit. Use a spray bottle or a small bucket of water and rubber gloves and paper towels. Lower numbers of sandpaper are coarser so get the sandpaper wet and start with 400 and then rinse and keep moving up the grits until get to 2000+. You will be creating a slurry of yellowed plastic each time. For the pro look you can finish with plastic polish. The first time you do this might be a learning experience but the second time will take you about 10 minutes. Test on an inconspicuous area first!
