I watched a documentary once about the cold viruses.
Basically our bodies have several fighting mechanisms. We can't really avoid the virus/bacteria flying around but as soon as it hits us through the nose or mouth, our defence system kicks in quite quickly. If you're healthy and you have enough white blood cells and good metabolism, you'll be likely to fight most of them off. Because the mucus slows them entering our blood, there's enough time for your defense system to kick in before they get in to your circulation.
Except when you get them through your eyes. There is no mucus or anything to slow them down so it's straight in your system and blood circulation before youre body has enough time to fight back. You get them in through your eyes when rubbing your eyes and you have them on your fingers.
So I started paying extra attention to my hands contacting my eye balls. If I need to rub my eyes I make sure I use antibacterial sanitiser before I do it. I just don't touch anywhere near my eyes unless I know my hands are clean.
On top of that I take daily doze of vitamin C, even more so when I know there are bugs around. I pay extra attention to healthy diet as well when people get poorly.
I haven't had a cold since. I think it's been about 2 years. Everyone in the office has been full of it, this nasty cold that seems to last 3 weeks or so. I've been safe so far.
I'd pick Scottish Highlands. It's just the raw beauty that I love up there.
I would love any mountain area. Norway would be amazing too especially for it being always voted for the top 5 countries to live in no matter what the category. But I've never been to Norway. I've been to Scotland and at the moment, it is Scotland that is calling me. Shame threre aren't any jobs in the highlands. Edinburgh would do just fine too.
