Swim for your life and for your fitness

As crazy as it could sound: for life and for fitness. When you learn and setup good swimming form, you should, besides find out your cruising pace, find the sensation of flowing with the water. So try to roll your body with each stroke and stretch, but as soon as you master this, or most of this sensation, imagine that there is something that is going to catch your foot, propel yourself with 'fear' of being caught; it is pure adrenaline, and the fulfilling essence of complex and efficient speed. Glide and find fear. Give it a try.
