I much prefer swimming when there's a lifeguard on duty to supervise the safety of swimmers.
Definitely.  Pools and Oceans are places where medical attention and rescue efforts have to be given quickly.
Yes and lifeguards are strong swimmers and are trained in CPR.
It's a shame that often they don't get paid enough for what they do.  It seems that we don't really value safety if we don't pay them enough to live.
Yeah it's true. Especially when sometimes they even help with mountain rescues and EMS services.
