should I be afraid?

There are some small containers of cottage cheese in my fridge which have a best before date of February 19. I brought one to work today... and opened it. I sniffed it. Smells fine. I put a little dab on my tongue... that seems fine. I put a whole spoonful in my mouth... again, fine. Now, should I be afraid of cottage cheese that is supposedly well past it's best before date, but tastes, looks, and smells just fine???? Time will tell...
