I'm sure that men is more adventurous than women. because in commonly men likes challenge things and doesn't care of dangerous, = because, men comonly like challenges and don't care of dangers, but women likes = like safety. I think it is related with human history. normally men was in the war and had dangerous things. = In the past, men joined in the war and were exposed in dangerous things. men's brain is insensitive for dangerous, even enjoy dangerous things. = men are prone in dangers, they even enjoy dangerous things. men enjoy to meet own himself who is getting better than before, = men like to improve themselves physically and mentally. I know that many women also enjoy adventurous things, but normally women is reasonable and social creatures. they like cooperation than competition. Maybe women see that men's adventurous things is looks = look childish and nonproductive. there are accidents in extreme sports and somebody are died = somebody died because of it , but still many people enjoyed it . And most of them is = are men.
so I think men is = are more adventurous
