It started off with "we should have a first aid kit in the truck". That lead to Wilderness First Aid Training. Now we have a big first aid kit in the truck, and small ones in the other cars. I even carry gloves and dressings in my jacket on the motorbike when I commute.
Then I got CPR training at work. That lead me to look into the survival rates for out of hospital cardiac arrest. I'll save you the google - the rates are not good. Once again, TV has let me down. TV shows that CPR works most of the time. In reality, if you get CPR out of a hospital environment, you are toast. The CPR training at work also covered automatic external defibrillators. Did you know that you can buy those with flex spending money and Costco sells them? I'm thinking about buy one for my 60-something parents for Christmas. Unfortunately, AEDs also have a very limited application.
It's a dangerous world out there. Maybe I'll just wrap myself in bubble wrap.
