There's no way to write a subject line like that and not sound like a spam generator, is there? Nonetheless, here you go; three life-hack-ish tricks I have found useful lately:
1. Borax and sugar to annihilate odorous house ants (a.k.a. sugar ants or soil ants). You can find various methods for this all over the web, but basically you mix equally parts sugar and powdered borax (not Boraxo) with a little water in a small low container (I used bottle lids) and put it where the pesky ants keep getting into the house. They'll zero in on the sugar, take the mix to the nest, and get themselves and their nestmates killed by the borax. These teeny ants have plagued us ever since moving in, and despite regular exterminator visits, have been invading the kitchen this season more than usual. So in desperation I tried the borax trick, and hey! Invasion over! They swarmed the lid for about a day (which in itself was an improvement, since then it meant they weren't roaming the dining room table), then their numbers dropped dramatically. Fully worth the cost of a box of borax.
2. Alternate hot and cold water in the shower for overall well-being. This is an ancient custom, of course; the Romans with their many-temperatured baths knew of it, as do spas all over the world. (Those intrepid Scandinavians sometimes like to hop from their jacuzzis straight into a hole in the river ice. Naked. You're hardcore, people.) I'm more or less switching from 30 seconds of comfortably hot water to 30 seconds of "as cold as I can take it without screaming," back and forth a few times. The cold part is not particularly fun. But the process does seem to leave me feeling rejuvenated, and many people claim it's excellent for your circulation and immune system. So. Try it if you dare.
3. This isn't new, but is worth a repost, and anyway you can't have just two items on a list; you must have three:
my cure-all spice drink. Helps with headaches, digestive issues, bloating, colds, PMS/hormonal blahs, and probably more, given all the crazy-high levels of antioxidants in herbs and spices. I'm having a cup right now and my "been a long week" headache is already improving. We all might need it as Election Day draws nearer, eh, America? (Seriously, world, we're so sorry to have subjected you to this.) Be kind to each other out there, everyone.
