24. Only Swim With a Lifeguard on Duty
You may think that you are a good swimmer, and maybe you actually are. However, you are not immune to the dangers of drowning. At the beginning of the summer, when your muscles are not accustomed to the rigors of swimming, you may push yourself harder than you are capable and find yourself in distress.
The best way to prevent drowning is only to swim when there is a lifeguard on duty. Lifeguards are trained to recognize when someone is drowning and intervening in such a way that they will not get pulled underwater.
