I disagree about the weather. In what way is the Russian weather worse off than Icelandic one where life expectancy is pretty high. Most pathogenic microbes like abola virus cannot spread around fast enough under such extreme conditions.
Some other reasons:
6.Smoking.
7.Falsified products and drugs.
8.Overeating at night.
9.Bribes and extortions in hospitals.
10. Women’s greediness.
11. Alien abductions and what not.
The silver lining is that Russian men should not give too much thought how they are to live after retirement because it’s not what is ever to happen.))
