[Publius Valerius]

If I recall, when I was younger and through most of my life the "flu" was too common and I was hit several times with it.

Certain mutations of the virus are more deadly than others. While any type of flu can be deadly to the very young and very old, from time to time, certain strains will mutate such that they are deadly to adults. This may be one of those strains.

This may be one of those strains.

I see your point.
