Ingenuine flu... I've had it once or twice, and I wouldn't recommend it matey....

I've been around a bit (roughed it in a few places), and as a man of the world I can assure you - life has little worse to offer than an insincere streptococus.

In fact theres a saying:-

Give me a germ that's straight and true!
Straight of back and eyes of blue!
Then what care I, of streaming snot
bad catarrh, and fever hot!
An honest germ, with coughs of phelegm
And snotty sneezes is a gem!
