I went swimming to the city pool yesterday.
The pool is a heated pool with bathrooms.
I’ve swam about 3 times a month for a year.
So now I am able to swim 500m.
At first I was tired to swim only 200m.
But I can't swim front crawl.
I can only swim flutter kicks and breaststroke.
I think swimming and singing are similar.
Because in both case I have to take a big breath in a moment.
