No Preservatives - the beauty of the canning process.
Most of the above is due to physical exertion.
My jaws hurt because I decided to take up Haku's suggestion to chew stuff in order to build up head muscles (a preparation for when/if I have to go bald). I chewed gum vigorously for like.. 8 hours yesterday.
Not sure why my head hurts - probably from lacking sleep a little?
No idea regarding the cough either.. my brother's got a cold, but cough's usually the last thing to happen. I did sleep in too hot an environment though - that always makes me feel like crap, as if I just had a fever. Might have enhanced all of the above.
God Bless Painkillers. And a strong liver to break them down with.
