I love swimming and even more so now that I'm older and it's a low-impact exercise. It doesn't hurt my knees like running does.
Do you just swim laps or do any sort of other activities in the water?
Mostly just swim laps. In my younger years, I was on the swim team and competed locally, although inspired to compete in the Olympics one day.
What was your favorite stroke to swim?
Back stroke was my best and favorite. At first I would worry about sinking, but I was told since the body is only a little less dense than water, the water will support my weight during swimming. 
That's really cool!  Did you have to use any special clothing or equipment for swim team?
Nothing special. My parents did sign me up for swimming lessons though so I could develop good technique and confidence before competing.
What age do most children sign up for swim lessons?
It was first viewed that kids could not swim by themselves until they were 4, but now it's recommended that babies take lessons to prevent drowning which I think is a great idea.
That's smart!  I will definitely get my children started as babies
