Muscles could just be opening and closing the valve I guess?

I think the point is that the bladder is above where the pee comes out so gravity could be pulling it out of the body. Aiming upwards wouldn’t change this relationship because the pee is outside the body at that point. By being upside down the bladder is now below where the pee comes out and gravity would be keeping it in. By being able to pee upside down, he demonstrates that gravity is not a necessary component.

I think it can be demonstrated by aiming upwards with some extra pressure though. If gravity were the only thing pulling pee out, i wouldn’t be able to shoot over someone’s head for instance as the pee wouldn’t have enough kinetic energy. Thus gravity is not the only component.

I don’t have thumbnails set on my phone so I only ever saw the full image. That said, I looked at it without my glasses with my arm outstretched and I’m going to guess they saw either buttcrack or titcleft

This particular flavour of survivorship bias is also called the anthropic principle

In Ireland it’s Éire, while Iceland is An Íoslainn, so it doesn’t really work 😕

I have a colleague who is trying hard to do it, but it isn’t good enough yet fortunately. I point out as many issues as I can to deter him but it ain’t working.

No thank you, I don’t want to imagine this please

I like the idea that time machines are like phones in that you need a receiver to pick up the signal. A consequence is that you can only travel back to the time that the machine was turned on.

I use DuoCards for flash cards. The word games are FOCLACH (basically wordle in Irish), litreach (guess words from people saying them in 3 Irish dialects) and seafóid (basically Waffle in Irish). The games are all browser based apps so not in app stores, but DuoCards is.

ETA while DuoCards has built in flash cards, I usually make my own based on the words I learn from all the other sources, and get the translation and grammar details from teanglann.ie, tearma.ie, or nualeargais.ie

My experience is that duolingo is a good component of language learning but is bad as a whole package. I have that, a flash card app, daily word games, and a YouTube channel for a children’s TV network in my language. None of them individually would teach me the language, but collectively they reinforce each other and fill in many gaps. Alas, neither innovative language nor lingodeer have the language I want at the moment.
