Is A BP Of 112/62 Considered Low For A 45 Year Old Women?

I am a 45 year old woman who weighs 135 lbs. My blood pressure is 112/62. Is this too low? Over the course of a decade I lost 120 lbs, reduced my blood pressure (it used to be 160/110), no more arthritis medication, no more diabetes and no more IBS but my family is concerned that my BP is now too low....but I do feel great. : )
