What's in a man's head?

My nurse Mammy has me in bed resting 'for the good of my health'. I need to sleep but I don't want to so I'm thinking instead.
I'm wondering if men think as much as women. As in, I wonder if men's brains whirr as much as women's do or if they do whirr at the same rate then do they just think of way less complicated things? As a woman, I can tie myself up in knots and the more I tell myself not to think about something the more I constantly ask: why? what if? how? when? should I? will he? and consider: maybe, someday, I wish, I shouldn't have. It's completely ridiculous. I should be doing something constructive like reading or watching an interesting documentary or sketching or even knitting but I don't want to. I really enjoy thinking and wondering and figuring out and considering and using my brain and so I do just that. Sure it's fine. My subsequent need though, to share my thoughts with others in order to seek clarification can make me come across as a bit of a crazy I'd imagine. Ironically, I overthink like mad in order to gain a simple life. I'm not sure they go hand in hand! But sure, it's just the way I am.
Men though. I wonder if they just think about uncomplicated stuff like what's happening right now in their lives at this very second in time. I wonder if they ever read into things or if everything comes at face value. It's not that I think men are simple, uncomplicated, incapable beings but it's just I think women are terribly complicated and unnecessarily take routes around life that could so much more easily have been followed if they weren't accompanied by ridiculous over thinking. Or perhaps I shouldn't generalise. Maybe it's just me that has this infliction. No wonder my mother sent me to bed to rest! I'll keep the following quote close to my heart however:

“Poirot," I said. "I have been thinking."
"An admirable exercise my friend. Continue it.”
