Breaststrokers are said to be good in bed because of their strong legs and tight body. Science has not proven it (yet), but breaststrokers are rumored to have the biggest boobs (female) or package (male).
Breaststroke was the first stroke ever swum in competition, in England in the early 1500s. It is the third stroke in the individual medley.
