Yeah, my bro in Texas calls me an ostrich (keeping my head in the sand). Said I should have seen this coming. He is a prepper.
I only keep about 2 weeks or so provisions on hand. I just call him selfish because he has years worth of goods, masks, hardware, etc.
I am also a prepper, and have close to a year's worth of freeze dried and canned food stored, not to mention ammo, medicine, and water. I also had N95 level masks on hand because I do woodwork, so use varnishes, so always had a need for the masks. But I don't know that I would call being prepared for disasters "selfish". I would certainly not run out today and buy up all the read, toilet paper, and hand sanitizer I could find, but I think it makes sense to slowly build up your supplies of basic needs to keep your family alive and healthy through a long term crisis. I also have a vegetable garden, and although I don't do canning, I have a lady friend who does can, so she cans vegetables for me in exchange for work around the house I do for her.
When I lived on the Florida coast most of the oldtimers I knew were always prepared because they had survived multiple hurricanes and have been through weeks without electricity and bare shelves in stores, so it had gotten me to thinking could I ensure my loved ones' survival with just keeping enough food, medicine, and other basic necessities to get me through a week or two longer than my weekly trips to the grocery? In most cases here in Tennessee, probably yes, although the recent tornadoes here in mid-Tn reminds us we can easily be without power for weeks, and will not be able to easily maintain perishable food. But it is the real catastrophes that we prep for. Same reason we purchase major health insurance plans. We can pay for trips to the doctor for boo boos out of pocket; but it is the catastrophic illness that could break the bank. I take the same approach with providing the basic needs for my loved ones.
Prepping can certainly be expensive when you go to the store and buy 2 of something, knowing you are going to put 1 item away, and possibly never, ever use it, and it also takes a lot of storage space to put back lots of supplies, so it is definitely a decision that has to be weighed, and you have to look at the pros and cons of it, and if you do choose to do it you have to decide how long you think you want to prep for. I laugh at myself sometimes because I originally started off thinking I needed to be able to keep us going for at least a month, but slowly increased my supplies until I ran out of storage room for more. And admittedly at times I have thought is this really necessary?
But the truth is it almost becomes an addiction because you are always thinking do I have enough of this? Enough of that? Oh well.
