How to save a life... (don't ask me!)

Wow the lifguard course is tuff, 8am -5pm ish everyday this week and many hours of swimming. all fun but alot of hard work. 
I swear I shall never undermine a lifegurds fitness ability (or what it once was) again! We have done many tows, timed swims, casualty recovery, 3m dives etc and I even fainted to add to the excitement and realism of the situation (was back in the pool 10 mins later, must have been this alien exercise idea). more tomorrow, I shal hopefull gain my RLSS NPLQ on friday...I'll let you know
