Things about our planet, especially geography, weather. Things about the body and mind; mainly physiology and psychology. Some hobby stuffs like chess, poker, aikido, fishing, camping. I don't like fiction and consider it a waste of time though I might sometimes take a look but it might take many years before I do it more than ten pages, and I do more looks into natural sciences that I am really not interested about like chemistry, physics, biology, but only a bit at the time though I have got addicted to them at times too and read many hours but I have corrected that. I also like to study or understand some languages, I like Italian most specifically, it being like English but pronounced as it's written and it sounds nice to me. Wikipedia, I could like that as I like information over fiction but I find most of the knowledge to be past history; I know better as do many others but such stuff can't be written there as it would be considered original. History, I didn't like that but rarely, while I might now be interested to know more than I did before but nothing much I need to know anymore and there are higher priorities and time and energy is limited.
