It sounds like OP developed an uncanny valley for diamonds.

In case Dr Rosenthal doesn't get around to answering you, you might find his answer to a previous question interesting. Given that he mentions suicides peaking in the summer, it seems like you're not alone. https://www.reddit.com/r/IAmA/comments/nma1x0/im_dr_norman_rosenthal_the_psychiatrist_who_first/gznexj8/

Ok, this is probably a strange question, but at least it will be unusual. So, I do live-action roleplaying as an alchemist and want to make a wakefulness potion (so, coffee) that is 1) very strong (people will get about 10 ml max, so it should pack a punch 2) does not require electricity (I can use fire for heating up stuff though) 3) preparation is fairly involved / has ideally an unnecessarily high amount of steps, so I can present it to get my mastery in alchemy 4) does not require very expensive material, or material that looks too obviously modern (it's a medieval-ish fantasy setting, something like an old hand grinder or a manual dripping thingy works, a french press, imo, does not).

For now, I was thinking of hand grinding coffee, leaving it to cold brew at ambient temperature (in July, so it can get fairly hot) for 18 hours, filter (with a simple ceramic filter + paper filter), and, er, can I add fresh beans and cold brew again or is this a terrible idea? Anyway, on the side I make a syrup (so heat water, put a lot of sugar in, leave at a boil for a while so it reduces), and then mix 9 parts cold brew / 1 part syrup, maybe add a bit of edible glitter. What do you think? Any ideas for making this more complicated? Thanks!

No, though the app is aimed primarily at veterans it seems to be open to anyone.

You make a good point about running. I'm glad you don't, and instead take all these amazing pics! Still scary to see though!
