I heard some where way back that if you are doing a exercise like swimming for the aerobic benifit. If you stop for more then 15 seconds ..say to talk to someone..you lose the benifit from the aerobic part of workout.. Any one heard about this?

I thought it had to do with being impolite right after…._____.....meaning it was impolite to leave before 15 seconds had transpired……;)
