Seems like those that live in San Pedro should be getting enough Vitamin D from the sun? Up here, not so much . . . I started taking Vitamin D a couple of years ago, and have enjoyed much better health than in years previous. That said, I get a flu shot every year too. Since I started getting the flu shot, I haven't returned from travelling only to find myself come down with a horrible flu/cold/bronchitis, which used to be pretty much par for the course. And all that said, I've also become a fanatic about wiping down my area on the plane, with anti-bacterial wet wipes. Yeah, I do get funny looks from people, so what?
Have also had seat mates ask if they could get a wipe from me.
Perhaps I should buy stock in the product?
