Your comment really doesn’t paint an accurate picture. I don’t thin op is right, but I don’t think you’re totally correct either. The life expectancy in Russia increased after the Bolshevik revolution because it had been decimated by disease, and a civil war for the years before that. The increase in life expectancy had nothing to do with communists coming into power. It certainly had nothing to do with industrialization that didn’t really get going in Russia until 1930. It had everything to do with the end of the civil war and global medicine advancing.
“Dire food shortages, hunger and famine were further exacerbated by the outbreak of several epidemics. Between 1918 to 1922 there were 2.5 million deaths as a result of the typhus epidemic…
Population figures fell by 35 million and were estimated at 139 million in 1921, a direct result of the war, famine and epidemic diseases.”

I have both in ear XM4 and over ear XM5s and I don’t like either. The xm4 is just too big and too heavy. It feels like it’s barely hanging onto my ear. I’ve tried using the for running or bike riding and they fall out. If you try to force them to stay in your ear it can wedge itself in too tight and get painful.
The XM5s are too tight and they hurt right below my ear if I wear them too long. The anc is good but I had some Bose QC35s before and they were waaay more comfortable and worked just as good.
I wish I had got the AirPods Pro and whatever new quiet comfort headphones Bose had now. Still thinking of switching.
