Breathing from both sides

Today I learnt to breathe from my left side for freestyle swimming.

I had been breathing from my right side all along, and was getting the hang of the breathing technique taught by Bee the last time.

I was now able to breathe in a controlled manner, and to relax or hasten my swim as desired.

So Lee thought I should try the other side.

It felt awkward at first because I was so used to turning my body to the right. But after a while, it felt ok.

I was then able to alternate my breathing: right, left, right and so on.

Lee said swimmers in long distance competition breathe from both sides of their body. If they just use one side, they're bound to hurt their neck.
