Alcohol had probably been killing them for decades before this happened, the same as smoking, they both knocked years off my life I bet, and I'm only late 30's.
The thing is, of all the years, this last one has been bar far the least amount I've ever drunk in my adult life (and also a few years before I was an adult). This year I've drank about 3% of my next lowest year, and that includes years when I've been in the gulf for 4 month (where booze was banned). Not smoked at all either, and that's me stopping that for good I think. For a lot of people this will have been a bit of a health kick.
But, even at 5,460 deaths in 9 months, that's 7,300 for the year, which would have been around 6,275 before the 16% increase.
So, the deaths are up about 1000 for the year, but I also bet a large portion of those are from depression of people losing loved ones, or them being in hospital in a bad way, I would be surprised if the lockdowns were responsible for more than 2/3 of that increase.
The stats support banning booze more than they do banning lockdowns, as the lockdowns have been there due to the 100k covid deaths.
There will be other things like this that will add up, but none of them compare to or will ever add up to what happened last April, when we were having double the deaths we were meant to be having, and that was nothing to do with booze, car crashes or suicides.
