Oh, I love to swim, but not in the pool.
In the summer I like to swim in the lake, I feel very comfortable & relaxed during swimming.
I also like to dive, watching what's at the bottom.
In my opinion, swimming is the most pleasant sport activity.
Yes, I have done a lot of swimming.
The furthest I ever swan in a pool is 5 kms.
The furthest I ever swam in the open water is about 4 km.
I think it is still one of the best forms of exercise there is.
