BTW, I don't drink coffee. Yes, it's quite unusual for an Italian.

Very unusual indeed. I started drinking coffee around my 4th, maybe my 3rd already, although I can't remember drinking coffee at that age, but I do when I was 4 - my grandma used to make a great latte, which was considered acceptable for kids.  And I spent about a year in Italy, totally spoiling me for coffee, plus, my daughter was a barista at the time I used to work in the town where she lived and worked back then ....

Regardless, I am very steady when it comes to photography, or the few times I did shoot (pellets actually, target practice type of thing). I tend to be able to shoot at shutter speeds 1 or 2 stops slower than most other people, and get equally sharp shots. And that is with or without coffee .
