Not a bad idea, if one can afford it. But most people can't afford it.

Yes, I do and am fully prepared.

I have a pantry full of chocolate.

I feel the biggest threat is the Anti-vaxxers. Mutated measeles could wipe out a lit of people. Just imagine if someone released a small pox influenza cross.

Not any more.. Was born in a (US) west coast target. Moved away just far enough to ‘survive’ a twenty megaton airburst over my hometown. So dug in, literally.

Planted an ..eden (we know the concept), and preserved the harvests, bigtime! Wood heat, spring water, food supply, blast-proof basement/ garage, and firepower..

Never needed it … becoming proud of Humanity ..even the russians. Anymore, no fear, though the world’s still in MAD (Mutually Assured Destruction) mode…

No current threats beyond economic in my newest location. Might be concerned around a port city, but not much one could do to prepare, if only for a ‘dirty bomb.’ China will soon catch up, and Russa’s ‘rust’ is a concern, but for now, launches would be accidental. If not - the aggressor would be toast ~

I think it will most likely be something we bring upon ourselves that will cause technology to fail indefinitely. Our modern society is far too dependent on an extremely fragile electrical grid, limited fossil fuels, and a vulnerable data network. A massive solar flare, viruses, or EMP's could all hurl us back into the bronze age in a matter of days or weeks.

Beyond keeping a modest supply of clean drinking water, about 30 days of food, medicine and first aid supplies, and a few thousand rounds of ammo, I don't get too worked up over it. I figure if the lights don't come back on by the time my 30 to 60 days of supplies run dry, I'll probably wish I was dead soon after, anyway. I simply don't have the skills to survive off the land, long-term. Neither do 99+% of other people in our modern society. It will be pure hell pretty quickly, and I don't think I would want to stick around for that for very long.

No, especially if you want to live a normal life in regular society. First, what are the odds any individual survives let's say the zombie apocalypse, then what comes next? If you do survive a catastrophe of a war, and you have some medical and mechanical knowledge, everything you need will most likely be available in any left over buildings (No guarantee a prepper's place will survive either). Go take what you need.
This is not the same as preparing for a couple of weeks of bad weather.

Those people are generally right wing nut jobs who think zombies and democrats are after them. Too bad zombies eat brains and would starve on a republican.
In Houston the main concern is flooding and hurricanes. Be careful where you build and stay prepared during hurricane season.
