I noticed you have Age displaying in a user's profile via their birthdate but you also have it as a profile field.....I think the profile field should be removed. It seems redundent and un-neccessary.
Right, the point is to not have the Profile field one that a user has to MANUALLY set and to just have the one from the birthday set. So if the user has their birthday filled out their age is calculated automatically through that and if they don't have their birthday filled out then they probably don't want you knowing their age anyway.
