I remember the Swine Flu of 2009 very well, as it is the last time I remember almost being ill. I was in a band at the time, we were all around ~17-18 years old, sharing beers/cigarettes/joints etc... everyone apart from me was ill and had kidney pains, was sneezing/coughing with a heavy chesy cough etc... one evening after practising with them for hours in a city practise room I noticed I had a tickly throat forming, so I consumed a fair bit of raw garlic, raw onion, extra virgin olive oil, and lemon juice (maybe some ginger too), and I was absolutely fine, it destroyed all of the viral matter before it got past the earliest of incubation stages.
