Harry: recently, someone correctedthsi: "In 1862, a cholera epidemic broke out in Edo, and several disciples of the Honinbo house caught the disease. Shusaku involved himself in caring for the sick, which resulted in his catching the disease himself. On 10 August 1862, still only 34 years old, he died." by setting the age to 34. Is this correct? In Japan, how old is someone when they are born -- zero or one, years old?
