I am not sure where to post this. It is a study on how factors can influence your Death. It asked question that effect how you live and will give results considering change some life factors. It may be fun to play with it. Sorry to say it does not treat TS/TV or eunuchs. Have to wing it I guess.

Sure the study is with a lot of holes. Other studies that have other results.
