biochemist Boris Zbarsky and anatomist Vladimir Vorobiov worked night and day to preserve the body so that it looked as it had done in life. Ever since, Lenin's body has been checked twice a week for deterioration. Every 18 months it is taken to a laboratory beneath its mausoleum to be undressed, examined and immersed in preserving chemicals. Nowadays, Moscow's 'mausoleumists' earn most of their money by preserving the bodies of dead mafia bosses.
Why do they preserve the bodies of dead mafia bosses????
Dunno. I just Googled quickly to find a photo 8-)
