If I showed this to my Dad you would have an instant friend for life.
Mine too. My Dad would have thoroughly approved of that.
All the comments about getting the last squeezes of toothpaste out of the tube reminded me of how much easier it was to do this when toothpaste tubes used to be made out of a mixture of plastic and aluminum, and retained the shape they were bent into. Perhaps a few hardy souls even remember when toothpaste tubes were made entirely of metal (a mixture of tin and lead) up until WW2.
I don't buy paper towels at all. I use rags for wiping floors and surfaces, and if I want to use a paper towel, use a few sheets of bathroom tissue instead.
For the most part, I don't go to any great lengths to be frugal. My lifestyle in a 285 sq ft studio with just a bicycle, my feet, and the occasional bus or train for transport seems to have frugality built into it. I don't have a TV subscription, and my total phone + internet bills come to $35/month (less if I don't call much long distance). On top of that, my rent is cheap (for the area). Because my main recurring bills are well under control, the extra savings involved in making a tube of toothpaste last longer, or using less bathroom tissue/paper towels would be minimal compared to the money I save by not buying a car, for example.
I don't have a car, and I don't have HBO/Discovery etc etc, but my personal luxury in the winter evenings is settling down with a nice cup of hot coca spiked with whisky. Heaven! Gotta live it up from time to time
