Why did Stalin lower the age of conscription?

On September 1939, Hitler invaded Poland. Two days later, Britain and France declared war on Germany, and the war has become a reality. Stalin accelerated the preparation of the Soviet Union. So he lowered the age of conscription from 2 1 to 19, and the number of Soviet troops increased to more than 4.2 million.
