Hi Welcome to healthcare magic...
I think right food , exercise and meditation
would be right mix for a healthy life.
With age u need to concentrate on health and should take care of what u are eating , go for regular exercise and meditation for mental peace.
U can also get a general health check up at any hospital to rule out any common problems like anaemia , diabetes
Can also go with a multivitamin
syrup to boost your health.
Hope it was helpful.
