What is john rogan age?

As an AI language model, I do not have the current information about John Rogan's age, as he passed away in 1905. However, at the time of his death, he was believed to be around 37 years old. John Rogan was known to be one of the tallest and largest human beings ever recorded, measuring at 8 feet and 9 inches in height. He suffered from acromegaly, a condition that resulted in abnormal growth hormone production, leading to his extraordinary height and large body size.
