Add Extra Fields At Registration FOrm

Is it possible to insert more registration fields at Registration form? Like Born, Country, Height, Burst, weight etc. I wants to take require information from user who wants to register them self on our website.

Please let me know.

If it is not possible to show these K2 User's fields on Register page, then is it possible that user can edit them on their profile after get login?

Please answer me. My web URL is mangiteramedia.com

I think you will have to disable k2 user profile and install some new joomla extension for that
