Majority of my problems have by solved by not having Nvidia graphics. Personally Linux has been great at extending the life of old computers for me. Linux mint runs a million times faster than windows 10 on my old machines. But it also helps I am fairly tech literate so problems that come up don’t register as a bif of a deal to me compared to others.
But it’s not that simple. 100 boiling is only true at sea level. At 530 (~1750 feet) it’s 98c. At 1500m (~5000ft) it’s down to 95c. At 3000m (10k feet) it’s just under 90c. Ocean water freezes at -2c. Fully saturated salt water freezes at -21c.
