Shocked! Moreless, Invincible, everyone...

 Hello-o  Nothing earth-shaking really, but  I couldn't resist.  :-)  Two questions:

I am getting shocks all the time now, the last day or two, now that the dry  and cold is upon us--and this is even boiling water for humidity. And so on. Is it  likely just a humidity problem, or could there be something else?


Second question:
Are there any good natural sources of vitamin D...  for vegans? other than the sun, I mean. We don't get enough of that in winter. I find myself wanting some good  naturally-smoked salmon about this time of year--but my son is all vegan.  In other words, he won't be taking fish liver oil...
