National Programme for Health Care of the Elderly (NPHCE), Ministry of Health and Family Welfare had published a guide book for the health and fitness of Senior Citizens.
It is a well compiled guide which talks about the typical problems associated with ageing while also sharing tips on how to remain healthy and fit.
Though there is enough information about health and wellness on Google but as an initiative from the Ministry of Health and Family Welfare, this document seems to be well compiled and the people behind the efforts needs to be appreciated for the same.
The documents can be downloaded using the links or can be viewed below
