India's elderly are worried about their social lives

Rekha Singh and her husband, Col. R.D. Singh, traveling in Turkey two years ago.

(CNN)Rekha Singh lives with her husband in a New Delhi suburb. Her sons left home for work four years ago, and the couple has been trying to manage their lives as best as they can.

In India, facilities like public transport and wheelchair assistance are few and far between, meaning senior citizens are often confined to their homes. Singh is worried about her and her husband's social lives, more than their health. She misses social interaction, entertainment and shopping.
