I am not a woman for I possess much longthick trunkiness, but I can contribute for I do single by choice. An estrogen only forum is not the best place for this discussion for that assumes my contributions are void.
1) Shower head bag of cola. Take the thick rubber bands from stalks of celery and put a sandwich bag filled with coca~cola around your shower head. Those of us that have lived in the same place for more than a year know that your shower head will go to hell in a year and a half with hard or city water. Doing the bag of cola thing every six months overnight will keep your shower head like new.
2) Shoes are dangerous. The Japanese aren't perfect by any means. They like a lot of strange things in vending machines, but they do have a tradition that makes obnoxious sense: Don't allow shoes past your foyer. Shoes are great, but socked feet will keep your carpet, even if it's an industrial strength berber, alive and vital much much longer.
3) NEVER allow smoking in your home, even if you are a smoker. Smoking, even if you are a die-hard, refuse to quit smoker, creates an insane amount of work in the upkeep of your domicile. Outside of the fact that it annoys non-smokers, it means that any event that causes "sweat' in your home, like a malfunctioning cooling or heating system, or a child's water pistol party will create unsightly streaks on your walls. Not to mention the immense life reduction you'll experience with electronic equipment like coffee makers, televisions, microwaves, and especially computers.
4) Never neglect filters. Filters are there for YOU, be they furnace, air conditioning, washer, dryer, etc. neglecting filters is a great way to reduce the effectiveness of the given device, and also provide a breeding ground for airborne illness. Always check and clean/replace filters when necessary.
Hope this helps.
