It just occurred to me, the other day, how amazing wells are. I think i always just used to think of them as some sort of large underground bucket, that only held as much water as their volume. Out of the blue, it struck me that they're actually mining the aquifer - the level of water in the well is the same as the level of water in the rock (it might take a while to trickle back in after you take some out though). That's a lot of water. I can honestly say i have a newfound respect for wells.
Btw, if you're wondering why i'm started using capitals, it's cause i'm doing this on my phone and it automatically does it.
