My gr10 computer teacher was so tired of kids stealing those balls from class that he mass ordered a big bucket of them so he could replace them. One day he was showing me the massive tub he had. I told him that was really impressive, my collection isn't nearly that big yet.

:/

After my second colonoscopy, I was cleared for 10 years.

We'll see if I live long enough for a third.

Recommended age for colonoscopy is 45, I’m pretty sure there are people younger than that who had mice like these. They were still the default well into the XP era.

I used to just take like a piece of plastic and scraped off the little rollers... Not sure what a q tip is gonna accomplish. That shit (dead skin cells and sebum) gets caked onto the rollers....

The oldest mouse I've used was an optical mouse, which required a special optical mouse mat. It came with an SGI Iris Workstation.

Edit: added link to a page describing the glorious Iris 3000 for your viewing pleasure. Starting that thing felt like a Tupolev was taking off next to your desk. It was quite something. I saved one that was getting chucked, and found a place for it in the local national tech museum.

I don't care how well you clean it, I don't want the dense sphere putting back in.

Sure we're old and have to shit all night once a year, but we've got wisdom now!

Seriously, do get a colonoscopy, when appropriate. The risks are minimal and the reward is not having to go through years of chemo, radiation, and surgery and then dying of colorectal cancer.
