What are peoples 'special' interests?

Im curious to know what other peoples interests/hobbys are.  Recently I have been studying/growing mushrooms/mycology.  

Before that, it was keeping/breeding tarantulas and invertebrates.  I also have a vast knowledge of insectivorous plants.  As a kid, i practically knew every football player who played in each team.  Was obcessed.  Not so much now.  

So, what is everyone else like to study or spend time one?

  • Mine have been/are: Stargate SG-1 (this is like my forever one and one that since it became an interest never went away, I doubt it will, it has been about 20 years now!), Flowers & plants and their identification, animals and insects, specifically moths at the moment and collecting seaglass (I don't know if the collecting is a special interest as I don't 'find out' much about it, but do it for hours and hours and hours, in any weather if very focused on it until made to come in)
