Will Butley

 was a patient at the Huang Ti Clinic. Born in the 17th century, he found the secret to long life while in the East Indes Company. This allowed him to live for ~300 years - although by this time he was essentially in his 90s.

He was gay - with him having a relationship with Ron Sharpe. He often was walked around the clinic by Sharpe. He knew the incantations that created the liquid that kept people young. (AUDIO: The Tao Connection)
