Amazing Savants

Orlando Serrell is an acquired savant. An acquired savant is someone who displays traits of a savant after a head injury that affects central nervous system. Unlike savants, acquired savants don't suffer from any brain-related illness until they suffer from a CNS injury. 

He began to exhibit savant characteristics after he was hit on the left side of the head with a baseball when he was 10-years-old. Soon after he came to realize that he could perform complex calendar calculations. He can also recollect the exact weather conditions every day since the accident.

Luckily for Serrell, the injury didn't affect him physically in anyway. He said he had suffered from a headache for some time, but that disappeared after a couple of years.
