Smoking no, never. I was a heavy drinker in my teens and 20s, gave that up because I was getting fat (I’m vain, deal with it!). At that time, I started taking MDMA and speed. It was the late 90s, so it was a pretty standard for the rave and alternative scenes at the time. Gave that up when I got Menieres disease in my early 40s. Now I have one drink once or twice a month, but mostly drink plain old water.
I wish my SO would understand this… she leaves me in the dust (see also comment below)
I’ve worn progressive lenses for nearly 10 years now. I did get one pair on the cheap, and they were truly awful, unusable. That’s when I figured out that going cheap with progressive lenses isn’t worth it. That may be what has happened to you. Even with good lenses, it takes me a few days, maybe a week to get used to them when I get a new pair. Stairs are… difficult though, especially going down. I live in a busy European city, so I use public transport a lot, and that means lots of stairs. I can no longer run up and down them like I used to.
Yeah, by all accounts, Newton was a bit of shit. He did a proper number on Robert Hook.
