Ugh, good luck with that, Andy. I always have all the water I need for my breakfast on hand immediately after my meal the evening before - water for porridge, a cuppa tea and a coffee. Really crucial, that
I probably don't refresh my water supplies upstairs regularly enough - I'm sure the bottles are of the type that leak molecules, and since they're stored too long, that won't be good. But microplastics are everywhere, and I believe that aerating the water by pouring it from pan to pan is a good way to "bring it back to life".
I'm having a bit of a day off today, other than cooking some brownie-type chocolate yummy things (at least I'm using up supplies so I can replace them). I meant to be doing some weeding and digging up ivy roots from a new section I have to take care of, but the weather down here is *horrendous*. Not bad enough to flood, so not really very bad at all compared to what everyone else has been through, but bad enough for round here.
