I am almost 70, exercise six days a week for over an hour, am in very good shape physically but my bone density still went down.
Ndiphuthaphutha iminyaka engama-70, ndizilolonga iintsuku ezintandathu ngeveki ixesha elingaphaya kweyure, umzimba wam ukwimo elungileyo kodwa ubunzima bamathambo am bona buhlile.
