Singlepicky:
Great question:
I thing the answer should be based on the age at which the pool of available single men becomes significantly smaller than the pool of avail single women in any specific circle.
I’m afraid to post what age i believe is the appropriate age but suffice it to say that it’s much younger than 30. That’s not to say that a 27 year old girl should run to date a 45 year old guy.
I line i recently heard and it makes a lot of sense is as follows. when you are 24 date like you are 28. When you are 27 date like you are 32. It will give you the best chance to make sure that you are not single at reach 28/32.
The implication is for each and every individual to apply to their own personal situation.
