I like to listen to podcasts, documentaries, etc to challenge my own thinking. I recently watched a youtube video by Rollo Tomassi on the hypergomous nature of the female brain. How they are continually (subconsciously) looking for a better mate. It is clear from watching that not all women act on it, but it is deep rooted in their biology. It's an interesting viewpoint on marriage / relationships. I don't click on or post links on reddit, but if you search 'Rollo Tomassi Hypergamy' it should come up. I've just been thinking of staying single for the remainder (i'm 46 and done having kids). Have a great one men!

P.s. another interesting one is a Ted Talk called 'Cancel Marriage' by Merac Michaeli' (who is a female).
