I think that article is about two separate issues: avoiding the common cold, and "healthy eating". I don't see the connection, but clearly the author does.
I see I already posted my 2p's worth about a year and a half ago, so I won't add to it. Except to say, every year at about this time I get pestered, by my GP's surgery, to take the flu-jab (being over 65 I'm entitled to a free one). I always refuse. Am I right to do so? To me it's just another medication (and I take enough of those already!) of uncertain efficacy (how many different strains of flu are there - and how many vaccines?). I haven't had a 'proper' flu for years anyway. The doctor uses scare tactics ("people die from flu"
): quite true - but there again - he's got boxes to tick no doubt....
But the common cold! Yes I do get those - and I call it a cold, not "man-flu" - but it's still annoying. Especially if I get a persistent hacking cough which goes on for weeks after (hint: if you use Salbutamol, that helps to ease things a bit)
. So I'm still waiting for the vaccine against the common cold
How much longer?
