1. Diet to maintain my blood pressure naturally. All these years my blood pressure used to be 110/70 or 120/70 till May 2011. I am not under any medication. Today when I checked my blood pressure it was 120/90 and I got very concerned about it. Does breathing exercises if done wrongly affect blood pressure and pain in the chest cavity ? 2. Please also recommend some exercises for my age to maintain bone health and good health in general. Thanks.
