Chatto's rock hard physique can be attributed to his Combined Cadet Force training at Eton college -- a program that prepares students for military service. Prince Harry also trained in the CCF at Eton before signing on to the Armed Forces. 。

Unlike Harry, it's believed that Chatto will be attending university before his service, and is rumored to be enrolling at the University of Edinburgh.。
