Why is it that only 10% of Lenin's remains, which three generations of Russian scientists racked their brains to preserve at all costs, are now left?

There are several reasons. The first is that Russian technology at the time was limited and embalming techniques were not in place to protect the body well. The second is that the Russians did not manage Lenin's remains properly, leaving them subject to a lot of human damage. The third is the erosion of time, the power of age is relentless. Even living people can't resist the erosion of years, let alone a corpse, so Lenin's remains were gradually destroyed, little by little.

We all know that Comrade Lenin is a famous leader in Russian history, under Lenin's leadership, Russia held the very famous October Revolution, overthrowing the Tsar's autocratic rule, so it can be said that Lenin is a very influential figure in Russia. When Lenin was alive, he worked actively and often traveled around the country without getting a proper rest. Long time work, let Lenin's body can not eat, and then Lenin had a stroke, although the stroke, but Lenin did not immediately hiccup, just reduce some of the workload.

But then had another stroke, and after this one, Lenin passed away shortly afterward. Instead of putting Lenin's body in the ground, the Russians embalmed Lenin's body, which was a very cumbersome process that took not only time, but also a lot of money. The end result was not very good either. Plus the remains were allowed to be vandalized due to poor management.

So Lenin's remains, in the process of the passage of years. gradually destroyed, the body is now handed down is not complete, many of the body parts are composed of some chemical materials.
