All you mentioned about age, looking, fertile ability, fertile period, economy situation, religion, educational background, family belief and so on are not resources in one's love or relationship balance sheet, if you got a diamond ring, that is for sure resources, haha, the very obvious asset is spouses, current or long term, maybe they are useful assets, maybe they just look like assets but made up of borrowed stuff from outside and probably emotional bank if not good in managing, so they are actually liablities in the form of assets. haha
Anyway, time has value but opportunity has cost too. However, there is no doubt for you to love thinking by means of time. :-))
