Tezuka, Shotaro, and Nagai were extremely workaholic. Nagai's workload eventually decreased. Tezuka used to even work in parties or trains(when he made Crime and Punishment). He also can draw perfect circles without the need for any equipment. I firmly believe that his art style was his choice rather than what he really can do. Shotaro made 770 manga, while Tezuka made around 700. They worked themselves to death.
