text: who 'invented' swimming?   \nwhy was it needed?\nare you kidding?\ncan you really be this thick?\n\nok.\n\nswimming was invented by microorganisms who thought it would be a good idea to move about in the water to find food and get some exercise.  these little critters evolved (okay I skipped a bit) into human beings.  cavemen (and women) probably swam to catch food or to escape predators.  \npeople keep swimming today because it's just so darn much fun, and an important survival tool.\n\nduh.
