I suppose an opsimath is what I am, having gone to school at the age of 49. I hope I will continue to learn new things for the rest of my life. Study is not the drudgery I thought it was in my youth -- but then today I get to pick the subject.
An opsimath can refer to a person who begins, or continues, to study or learn late in life. The word is derived from the Greek οψε (opse), meaning 'late' and μανθανω (manthano), meaning 'learn'.
Opsimathy was once frowned upon, used as a put down with implications of laziness, and considered less effective by educators than early learning. However, the opsimath population is increasing in the USA, and the emergence of "opsimath clubs" proves that opsimathy is no longer looked down upon, but is in fact desirable.
