I have a lote of hobbys... , normally one day I begin with one but later I stop and begin with another xD .
My most stables Hobbys are:
-Photography
-Read books
-Kendo
-Learn about new things
sometimes I enjoy watch my environment and how it's her behavior, you can learn , watch and enjoy a lot of things that pass unobserved.
Sometimes I tend to be serious because something or someone caught my curiosity and I try to... mmmm ... we can say that I try to "understand" it
