I was just wondering which I would have found more believable 40 yr ago:Could someone break 19 for a 50 free or could a 60 yr old break 50 for a 100. Both would have seemed incredible,but I think the 50 time would have been more believable as times kept getting faster,but no one had ever heard of Masters swimming,let alone that we geezers could actually swim fast.:cheerleader::banana:
