its fear thats stopping you. go join a local swimming club or smth, they will get you so you can swim till you dont drown!
when you do swim, keep your body as horizontal in the water as possible, dont let your legs drop down. this means you are less streamlined so you have to do more work to move, and also, instead of just pushing across the water, you are actually pushing up and out, so you are wasting energy
If I am asked what we are fighting for, I can reply in two sentences. In the first place, to fulfil a solemn international obligation . . . an obligation of honor which no self-respecting man could possibly have repudiated. I say, secondly, we are fighting to vindicate the principle that small nationalities are not to be crushed in defiance of international good faith at the arbitrary will of a strong and overmastering Power.
