4 for sure. 1 is a pain in the ass when you get in a 5 speed and you’re used to something else. I subconsciously double-clutched once and almost released the clutch in reverse gear at 70 once with that.
It’s lacking all sorts of minerals, electrolytes etc that the body needs. I doubt a glass of the stuff wouldn’t cause problems but if you only drink pure water then you’re going to start having problems pretty fast.
Yeah same. Personal preference I guess.
