Do you have urges to go to churchyards, graveyards and cemeteries. Do you like to walk among the tombstones, gaze at the mausoleums. If you do, you may have Taphophilia. don't worry it won't kill you.
No, it's not some dreaded virus or disease. It is simply the desire to learn and like and be in cemeteries and anything to do with funerals and their trappings. It isn't morbid, or disrespectful. Taphophiles have the highest respect and appreciation for such.
Don't be ashamed, come out of your tomb and celebrate your affliction.
