Post #37 is just listing basic steps to take...steps that take very little time...very little effort...very little money...and will not impact “normal” life.
Going into more depth is futile. Most people will do nothing their entire lives, always claiming that they are “too busy” (a grand irony...people aren’t too busy, just lazy and scared of deviating from their routines).
Which is to say, most people won’t even do the simple things. At most, they may buy a handgun, but really, they are doing that for crime or ego reasons or because it’s cool ... more than for a viable survival plan that they are following.
