Beauty? Good looks? Why does it play such a big role?

My question today is, What does beauty, and good looks really mean?  Sometimes we see couples together and they are not equally 'good looking.'  Does this mean the unattractive person always seek someone better looking?  If it's true love, looks normally don't play a big role.  Understanding someone's personality, being attracted to someone's mindset, and being comfortable with someone, those things matter so much more than just hot looks.  And I hope that in my life, this will also be the case.  Sometimes we are obsessed with being good looking, muscled, and we forget the smaller things in life, such as appreciating people around us, for who they are.   However, being healthy & fit should be motivating, and inspiring!  Looking good makes one feel good.  If your partner is "obsessed" about gym, then perhaps join her/him and don't feel left out.  You'll see, good looks will fade, but being healthy & fit will stay with you forever!
