I am a trained life guard! A lifeguard is a rescuer who supervises the safety and rescue of swimmers
That is quite an important job.  Was the training hard to go through?
It was ok but not too hard. Lifeguards are strong swimmers and trained in CPR/AED first aid
I know what CPR is, but what is AED?  I have never heard of that term.
It is a defibrillator. I have heard in some areas, lifeguards are part of the emergency services system to incidents and in some communities, the lifeguard service also carries out mountain rescues
Really!  I had no idea.  I just thought they worked at pools and beaches!  Is there specific training required for mountain rescue as a lifeguard?
