Nothing is impossible, but if it&#x27;s very hard most of people will not manage to do it on their own, it&#x27;s just a simple fact of life. Push them harder and just more of them will fail. If you throw a 100 non-swimmers in a pool, probably all 100 will manage to swim out alive. Throw them in English Channel and tell them to swim over to France, and most likely all of them will drown.
