You’re to old for the flu. That could be very dangerous at your age, be careful and rest. Sweat your arse off and plenty of fluids too.
Stay away from Dr’s offices/lab services (where I caught it), shopping malls, movie theaters and other high-traffic venues, when it’s circulating.

Good advice.
Back in the days when I would get the flu, I would get in bed cover up with two or three blankets, in the morning the bed was soaking wet but the fever was gone
