I find this amusing. We know that light has an impact on the body - so they make/sell lamps that emit light similar to sunlight, red light therapy, circadian smart bulbs...

Washing in the river used to be normal + good for the body - we do cold plunges now.

Probiotic supplements exist, we used to get those for free.

We're gamifying nature. Not saying it's a bad thing, just amusing to me that it used to be our entire lives and we're using technology to get it into our lives in smaller amounts.
