The site didn't tell you anything you didn't already know, it only clarified it.
Instead of denying information to keep yourself happy, why not use the information? My 69-year-old mother remarked earlier this year that if she didn't get around to some of her life goals soon she wouldn't be able to.
Did she say that out of depression? No, to live the life she wanted even more. She celebrated her 70th birthday bicycle-touring a wine region in France with my step-father, riding something like one hundred kilometers a day.
We can all do the same in our ways. In my opinion, awareness trumps denial.
