Preparedness will mean quite different things depending on the place you live in, weather, family composition, health status and so on.
In my case, I donīt have to worry in terms of natural disasters, Brazil is quite blessed on this aspect!
My preparedness focus on medical emergencies:
1. What will I need in case my mother needs emergency medical care
2. What will be needed if I need emergency medical care
3. What will be needed if something happen to both of us
When my mother got hospitalized, I was not prepared for that... I went to hospital with only my wallet!
Medical information, specific contacts, family contacts, medical contacts, cash, change of clothes, chargers, extra batteries, snacks, etc. All this must be ready, together and accessible in case of emergency and that is something I learned the hard way.
And what better way to handle this then in a TB based tiered BOB?!
