London water is pretty hard and bad for kettles, but ion exchange

My kettles seem to last quite well without any filters. And weren't there
some reports that hard water is better for health?

Only if you never drink milk or eat cheese.

I have known people on private soft water supplies so lacking in
minerals and calcium that they were prevented from using it. Didn't stop
all previous generations growing up healthy.

Pure deionised water isn't that good for you. If you read the MSDS for
deionised water you would imagine it was as bad as hydrochloric acid!

You have to consume large amounts of deionised water and almost nothing
else before it will deplete calcium from your bones. Certain sweet
yoghurt vendors play on parents fears to sell it with added calcium.

Sadly rickets is making a comeback due to the chips & pizza generation.
