I’d say probably about a 7. I’m good enough with technology to have been using Linux for the past few years without any major issue that wasn’t caused by the distro I was using. I still wouldn’t say that I’m great with it though, because there are still several things I don’t know how to do and there are probably also a bunch of things that would be useful for me to know but I just haven’t found them yet or even know that I need them in the first place.

If you aren’t already aware of them, you should look into something called “beer money sites/apps”. Lemmy doesn’t, at least currently, have a good place to talk about them but I’m pretty sure that Reddit still does. I haven’t used Reddit in several years but I think the most active subreddit was called r/beermoney.

I’m kind of surprised no one has said honey. While I can’t find exactly when honey was first used as a preservative, it’s believed that it was first used in ancient Egypt. I also don’t know if vitamin C specifically was ever preserved in honey but honey has been used as a preservative for fruit.
