>For example, usually yearly vaccines contain a couple of A strains and a B strain, whatever was most prevalent in the other hemisphere 6 months ago.

This bit of vaccine logic has never made sense to me given the speed of flu virus mutation. I mean you can get over the flu in a couple of weeks but then soon after pick up a brand new mutated strain. But it takes 6 months to pump out a vaccine for one set of strains that odds are are obsolete by now and one's body is already immune to through natural exposure?

I mean I understand what you're saying that there are virus sets in the vaccine one wouldn't necessarily run into but still. 6 months seems to be an awfully long lag time compared to the flu's mutatuon rate and even human natural immune response and adaption rate. So yeah this particular bit of logic never made sense.

But please if you have a sensible counter argument for why someone with a functioning immune system should bother then I'm listening.

Why this is relevant is your above explaination seemed to take yearly flu innoculation for granted.

Okay so ignoring the ego tripping below what im gathering is pure lye is a particular chemical potassium hydroxide but wood ash has large amount of it in it so when you dillute it in water you are getting a mix of chemicals with a high concentration of lye within it, tho it isn't entirely pure lye. How could one refine this process.

You're talking about deriving lye from ash in order to make soap. I was wondering about that. You said numerous metals end up getting oxidized in ash. So how does mixing ash with water give you lye specifically so you can combine with with fats and oils to make soap? How do you go from a random mix of oxidants to a specific alcaline chemical?
