Even thinking about a comet impact gives me a headache. World wide impact, earthquakes, tsunamis, fires raging around the globe, possibly years of “nuclear” winter, perhaps an ice age,? There’s the immediate effects, and then the aftermath to deal with.

What would I do ? PANIC !
Then start reading and researching: relocate, stockpile, team up with others, plant a garden, orchard and start up a farm.

I guess my approach is that I’d start to prepare as best I could to survive through the ordeal. In movies and fiction you always have a few characters who elect to just sit calmly on the front porch, hold hands and enjoy the show, I don’t relate to that at all, but I do accept that some people will want that.

I have a family to care for and I don’t think I’m ready to just give up, so its “prepare and struggle on” for me.
