Not having a will, and having a will, both lead to stupid probate court delays and expenses!
A few technical issues. Wills are designed to make lawyers lots of money whenever somebody dies. All sorts of unnecessary and time-consuming probate issues that eat up a substancial portion of the inheritance. Due to the corrupt system, and that probate really was only to insure that the dead's person's bills get paid, which usually the survivors take care of anyway, now the far better preparation is not a will, which is almost like not having a will, but to set up a proper Living Trust. There's a paperback book "The Living Trust" by Henry W. Abts III. I can't go into much detail, as I really wouldn't know how or have time to explain it all. The basic concept is, that when an individual holds wealth, when the individual dies, who then holds that wealth? So a complicated transfer is then initiated. But under a Living Trust, the person is their own trustee. When that person dies, their Trust does not die, and successor trustees are already named, so it's a much smoother transition.
Only you and your conspiractors are harmed? Oh, please do elaborate. Are these errors of carelessness, or of deliberate conspiratorial design? So all such people who might find some reason to cook up such recipes, never ever live in apartments, with innocent neighbors all around? Also an added danger of meth labs? Presumably not all are out in the middle of the desert somewhere? Isn't the entire history of the development of explosives, a particularly dangerous one? Only recently have they figured out how to make effective explosives, very stable and safe under normal handling. And BTW, I don't think I would prefer a job working in a fireworks factory.
I've heard that the old chemistry sets were much better than the ones for sale now. For fear of lawsuits, much of the "dangerous" stuff has been removed, leaving us with chemistry sets, that have very little chemistry left in them? Presumably if you are intended to blow yourself up, you'll have to try a little harder now, and know what you are doing? Often mixing chemicals can be dangerous, perhaps enough to at least wear some safety goggles. If certain chemicals are too reactive, they can splash onto you, if you don't mix them just right? Or release poisonous fumes.
I wouldn't imagine that a cookbook with that particular name, to be completely safe, but is it even less safe than we would have been led to believe?
