I do not have to think about it.
It is well documented that men take more risks on average than women.

One example of many on this subject. From the Darwin Award to the 90% to 10% prison population balance, men far outstrip women in risk taking. Of course some feminists do not like this fact, but they do not like distributed traits anyway.

There are some studies that seem to suggest that women take as many risks as men, or take risks in other ways. Questionable studies, that is.
I think its men.
men.
For the most part men however in recent years woman have started taking more risk.
