I also watch doomsday preppers. SOme of the things I think is applicable to my situation is yung making sure you have at least 3 days worth of water supply, some light food and clothes to be carried, a half-full (always) of fuel for the car and some sort of protection like bolo and guns (kahit handheld lang muna hehe). A portable radio and of course yung mga utilities like rope an swiss army knife.

In my place, the biggest probable calamity if a super strong typhoonand maybe a tsunami/storm surge but highly unlikely. Another crazy possibility is being attacked by chinese armies. hehehe
