the word blog is derived from web-log, where you publish a public diary of sorts to the web.
men have nipples because male genetics do not take form until later in the pregnancy, so males have female characteristics during early development such as ovaries, which become the testicles in males. this type of late development of male characteristics results in males having nipples.
males can also lactate (produce milk) with there nipples just like females, which would be an attribute of survival if the female is unable to nurse their infant.
