Actually people die from the flu every year.
It's very similar in that one's immune system is compromised, results in pneumonia, and unfortunately die on a ventilator.
I never said it was the flu, simply stated that strains are different and that's why you catch multiple colds each year.
That said, if you focus on proper nutrition and different methods to strengthen your immune system, you can potentially never get sick.
I fast, eat as good as possible, and exercise, I haven't been sick in years.
