How did people construct wells before modern drilling and how dangerous was it?
In: Technology
In some places, with [lots and lots of stairs](https://en.wikipedia.org/wiki/Stepwell#/media/File:ChandBaori.jpg) and to keep the water safe from people with poor balance or a fear of heights or drowning, [no guardrails](https://en.wikipedia.org/wiki/Stepwell#/media/File:Hampi_aug09_243.jpg).
I wonder how many slinkies are at the bottoms of those.
