The maturity factor is more at play i think.. and i guess age effects maturity. However it is not matamatical.. some pleople mature early then others..

and some people (like me included) still hold on to the childish things about certain things..

to be in a meaning relationships, I guess both the parties should click.. in one sense being able to communicate at a deeper level, and the mush talk happens =) in all.. like the old Def Lepard's sayin..

"you can never change your heart, you can only change your mind.."
