Sounds like a stuck button. Personally I would disassembly the device and have a look at the button and surrounding parts for any damage or liquid or debris at all. If there is any physical damage then an RMA or maybe replacement parts can be ordered (like you can buy replacement rubber if that feels worn at all). Otherwise I would ensure everything is clean and free of and liquids, stickiness or debris then reassemble the device. Even if nothing looked wrong I would test it again and see if the act of disassembly did something to solve the issue which it sometimes does for things.
IFixit has guides for the LCD and OLED versions and overall the steam deck is not very hard to disassemble compared to other small electronics. Though if you are unsure about this you may just want to talk to valve support first. If you accidentally damage something that could affect your ability to get an RMA.
The only things not linked to cancer are the things not yet been studied. Seems like everything at some point has been linked to cancer.
Sounds like a correlation... someone who eats one hot dog and drinks one soda per day is probably doing a lot of unhealthy things.
Yup, that is what it is. A correlation. So overall not really worth the effort involved IMO. Not eating any processed meats at all is not likely a big issue, but your overall diet and amount of exercise/lifestyle. I would highly suspect that even if you did eat one hotdog per day, but had a otherwise perfect diet for the rest of the day and did plenty of exercise, got good sleep and all the other things we know are good for you then these negative effects would likely becomes negligible. But who the hell is going to do that? That's the problem with these observational studies - you cannot really tease out the effect of one thing out of a whole bad lifestyle.
I hate headlines like this as it makes it sounds like you can just do thins one simple thing and get massive beneficial effects. You cannot. You need to change a whole bunch of things to see the types of reduction in risk they always talk about. Instead they always make it sounds like if you have even one hot dog YOU ARE GOING TO DIE.
