4 x African Grey, 3 x Blue Fronted Amazon, 1 x Yellow Crowned Amazon, 5 x Peach Faced Lovebirds, 3 x Cockatiels, 1 x Eastern Rosella. Possibly getting 3 more Rosellas (if I can find any!) in a few weeks as that one is lonely. He came with a couple of Cockatiels, and is sort of friends with them, but he needs his own kind as he wants to nest.
I do similar, I will use old stuff I know is wasting energy instead of replacing it. I've got 7 computers doing science calculations. I could buy faster ones that use less power, but I don't know how long it would take to get the money back. People who put in a new more efficient gas boiler (furnace for Americans) spend huge amounts to save very little gas, and the modern efficient ones don't last, so false economy for your wallet and the environment.
My parents are retired and they bought a slimline dishwasher (only because the gap was slightly too small for a regular one, due to bad house design). Dishwashers clean dishes better than by hand, and they save a lot of hassle. Even if you're bored, better to find a fun hobby than do manual labour.
