Times have changed.. I was 5 years old in 1973. I took swimming lessons at the local "Y" in Barberton, Ohio.
Week 1 Lesson 1: We put the bottom of our face under water and blew bubbles.
Week 2 Lesson 2: They put me on the diving board looking out over 10' deep water while the "instructor" begged me to jump into her arms. When I finally did, she moved away and STAYED away.
WTF? I think they would be arrested or shut down in today's politically correct climate. I could have drowned!!! But then again.. I never had problems with swimming or the water since.
