Stalin was not young for many reasons. First of all, he is grumpy and suspicious. If you refer to Cao Cao, you should know that such people are tortured by their own spirit even if they are alive. Moreover, this man's previous war was too heavy. Even if it was not the massacre of his comrades in the process of the big purge and the struggle for power within the party, it can be seen from his attitude towards his family that even his eldest son always suspected that he had killed his mother. It is said that his eldest son. After Zi was captured by the Germans on the battlefield, the Germans hoped to exchange him for Marshal Paulus. As a result, Stalin refused to trade paulus for others. The so-called tiger poison does not eat the child. Stalin used his son to achieve his wisdom, which is chilling.
Secondly, in the early days of the revolutionary struggle, Soviet leaders were exiled and imprisoned in Tibet, and their lives lacked regularity, especially poor food hygiene. Therefore, Soviet leaders are in poor health to varying degrees, leaving behind the root cause of the disease. Coupled with the busy work and war after the victory of the revolution, especially the top leaders were overworked, the health of Soviet leaders deteriorated, and most of them, led by Lenin, died long ago.
Finally, I have to say that Stalin's life is extremely unhealthy, which may be related to his Caucasian personality. His personal diet has not changed for a long time. He used to sleep during the day and work at night. Therefore, his children later reported that they never had lunch. If he takes a midnight snack as lunch, he becomes more suspicious in his later years, no longer trusts anyone, even refuses to eat cooked food cooked by others, locks himself in his office and uses electricity. Cooking on the stove, but in his early years, he never went into the kitchen or even washed the dishes. All he could do was scrambled eggs and cooked noodles. The aging of his nerves and body made his health worse and worse, and this living habit eventually led to his complete collapse.
