I'm asking because pro-atheletes are constantly sidelined by what is called "flu-like symptoms" I never hear this term used anywhere but professional sports. Why don't they just act like normal people and say they have the flu?
It means they aren't certain it is due to the influenza virus yet since other colds could mimic these symptoms.
because they don't have the flu; they have HANGOVERS and REHABILITATION NEEDS FOR THEIR SUBSTANCE ABUSE PROBLEMS that they don't want the general public to know about; so, they call it "flu-like symptoms".. haha
Heres the difference Mikey…….if you had the flu and there was a hundred dollar bill on your front lawn, you wouldnt give a monkeys uncle (you wouldn't care)………………if you had flu like symptoms, you would struggle with your aches and pains but still go out and get it!!!
