I mentioned up in the definitions section something about taking a CPR
class. This is probably the single most important thing I can think of that
anyone can do to help save lives. Sudden cardiac arrest affects nearly a
million people around the world every year, and while early defibrillation
is an important step (arguably the most important step), early CPR is
important too. It's six hours that you may never have to use, but if you
take the course and continue to take it annually to keep your ticket
valid, if you ever do have to use it, you'll know how. With the addition of
a first aid course, I think this should be required for all new parents.
Teach your kids how to call for help in an emergency, and encourage them to
learn CPR and first aid when they get old enough.
And please -- pretty please -- be careful on the roads. Vehicular
trauma is a preventable cause of premature death which really isn't very
pretty. So use your brain, and slow down out there.
