Much back & knee pain today. What'd be really novel would be for me to get more than 3 hours of sleep tonight.

Absolutely no idea. I believe it has a much higher butterfat content than cow's milk. Proper mozarella is made from buffalo milk.

Searching for a cooking oil with a high smoke point, I settled on good old-fashioned ghee, sourced from India. It's made with cream from a 50:50 mix of cows milk & buffalo milk. Haven't gotten it to smoke, it needs a temperature above 250°C for that, so it's ideal for those occasional frying jobs I do.

Doing a job at the Men's Shed today that really needed two electric stapling guns but we only had one. Then the Treasurer turned up, fresh from a visit to a tool manufacturer. He had another identical staple gun which was a refurbished unit that someone else had bought then returned for a refund because it was unsuitable.
The manufacturer can't sell that on as a new machine, so it's sent off & tested then donated to a deserving community group such as a Men's Shed. The manufacturer gets certain tax credits in this process.
So it's win, win, win. First a customer needs a tool for a once-off job, so he buys one, then returns for a full refund it after the job is finished, claiming the unit is somehow "faulty."
Then a Men's Shed get a few free virtually new power tools. And finally, the manufacturer gets a tax credit for offloading the item(s) to a Men's Shed.

You're being silly. I doubt very much you could annoy any of us here. We love you.

Beacause too many subsections would want to control it. The whole thing would collapse into chaos.

Any complex system which works has invariably evolved from a simpler system which worked even better.

A laser printer works like a photocopier. Uses a toner powder instead of liquid ink.

Not in the case of a laser printer. It's a powder.
