Known to who? I just did a quick search didn't see anything that like a scientist or physician said about this. Someone who describes himself as a 'biohacking educator' said it without citing sources though.

I can say the things I like, I like the same or even more (higher sex drive is one noted example). I can sit and program for hours now without thinking about other things. I assume this is what people who took Ritalin felt.

I do notice it makes it harder for me to get up and do certain harder, outdoor chores.

Yup, helps Gila monsters go so long without eating/doing anything
