I think it's also just individual differences. Some people are naturally more prone to RSI than others.

I get a bit of pain from long typing, especially writing prose, but it usually resolves itself pretty quick. However I knew a guy during my PhD who was like 30, used arm braces, a standing desk, ergonomic keyboard and mouse and took regular break on a timer AND was under lots of pain. That's bad genetic luck.
