I strongly disagree. The only thing that matters is distance and that's only because our genetics tell us if we aren't reproducing we are failing our species.
As someone (28) in a long term and happy relationship, also someone who's been through a lot of BS, let me tell you this: none of this matters. If this matters to you, you belong in elementary school, being a preadolescence. If someone tells you this crap matters in terms of a relationship with you, the simple answer is that they are not meant for you; why would you want to be with someone like that anyway? Age doesn't matter, height doesn't matter, you can travel to each other's location and have a plan for living close by/together in the near future, and it's the overall traits of a person that grabs you. Yes, physical appearance is your first impression, however personailities are the immediate second and make you want to get to know someone or run away really damn fast.
Just always be yourself, and only give time to those who strive to be with you.
