Do men have a biological clock too?

Not really, men can have children much later in life than women. Women know they only have a handful of years to have children, so they 'hear their biological clock ticking,' when they are getting close to the age when childbearing becomes difficult or impossible. Men, on the other hand, can have children basically from puberty into their seventies and even eighties.

I dunno about the whole having kids part, but for some reason my alarm clock changes every day of the week (mon, wed, fri, i get up at 6. and tue, thu, i get up at 6:30) and everyday, no matter what, i seem to wake up about a minute or two before the alarm actually goes off. Its quite strange, however there must be some sort of time keeping device that allows me to tell myself at night when to get up and then successfully be able to do it!

Yeah, it's when much older men start dating very young girls. Men tend to do this starting in their late 40's

yes but i think it's broken
