Opposites Attract?

Hmm... This morning when I was tuning into FM 100.3 the DJs were discussing if opposites attract really last? in terms of love... Apparently it has been realised that it is opposites that attract each other during courtship but when it comes to lifetime partners usually those who have similar characters, hobbies, styles... last happily ever after... How true is this? Well, to me nothing is impossible... It is up to the couples. Cheers!
