If seen as a hobby it isn't more pointless than 3d printing dragons.
2. I eat unwashed basil leaves and other greens growing outside, I eat them by first putting them under my tongue, my seasonal allergies (I am allergic to everything but mold) have plummeted over the last 3 years of this. The folk remedy of farmers market honey did nothing for me.
I did sublingual drops a decade ago and there was moderate improvement but for medical reasons I can't get a prick test again and I haven't been able to find a provider that will just make drops for me based off my original prick test.
It's impossible to find what plants capture the most environmental allergens on leaves or in edible flowers so I just have a collection, I figured that made more sense than licking a swamp cooler.
Anyway, I've gone from taking Allegra most days to only 2 months out of the year.
A lot of "specialization" looks more like enforced helplessness where the world around you seems to be full of mysterious magic outside your one specialty and often your specialty is very many levels of abstraction away from anything obviously useful to an end user (i.e. some brand of navigating office bureaucracy).
Many things aren't actually all that hard to do yourself nor do they take up all that much time or energy. And there are many things which aren't actually possible to distribute to end users so what's possible by yourself is so much more than what's possible to sell.
