His wife tried to abscond with their valuables, he said, so he gave the house to a niece, who ignored him after she got the property. Now his daughter is the only one who visits the 76-year-old retired teacher here in the capital of the southern state of Kerala, and that's just a few times a year.
"But she only comes to get money from me," said Nair, unshaven and dressed in a white lungi skirt-like garment and striped polo shirt, his voice rising in anger. "It's a blessing there are homes like this."
India, a nation that prides itself on the inclusive embrace of its extended families, is slowly accepting a feature long common in the West: elder-care facilities.
Social changes find more urban families rejecting traditional arrangements involving grandparents, parents and children under one roof, preferring life without nosy in-laws. Economics is also playing a role as more professionals work abroad or in large Indian cities, too busy to care for aging parents.
But things work both ways, sociologists say. More older people also prefer living with others their age, even enjoying a bit of romance away from the disapproving gaze of grown-up children.
"Life here is easier than living with my family in all respects," said P.V. Bhaskasan, also a retired teacher. "There's too much fighting in extended families."
As India's traditional social contract frays, however, seniors are also more subject to neglect, physical and mental abuse and depression. In 2010, 11,100 people older than 60 committed suicide, a 20% increase from 2008.
"In abuse cases, parents don't want to come out against their own children," said Anjali Raje, deputy executive director of the International Longevity Center in Pune. "So it's swept under the rug."
The idea of senior homes has long carried a stigma in India.
"I can't imagine sending my parents to one of these," said Sathish Kumar, 47, a Trivandrum rickshaw driver who shares care of his 77-year-old father with his brother. "It's rather tragic."
But that's changing, as more upscale gated communities for seniors, such as Mumbai's pioneering Dignity Lifestyle, offer saunas, aromatherapy, gyms and pools.
Because it's a relatively new concept, there's a generational difference, with those in their 70s and 80s generally more unhappy about living in a senior home and those in their 60s — a group that's had more time to watch society change around them — more accepting, said Dr. C.P. Muralidhara, care home manager at Utsav Retirement Resort outside New Delhi.
India, with its relatively young population, is still a long way from Western nations. Most extended families still live together, and even when grown children move away they tend to stay relatively close and visit often.
But the picture is changing, with the number of India's people older than 60, now at 96 million, expected to double by 2030. Critics say government planners are so enamored of the "India shining" narrative of its young people that they all but ignore the demographic shift.
"This is the government's last priority," said Roshan Jacob, an elder-care expert. "We're digging our own grave. It's a 200% crisis for India if we don't start thinking about this."
A recent survey by Economist magazine rated India last among 40 nations, behind Uganda, on "end-of-life care services," including access to drugs and caregivers. Only a few medical colleges in this nation of 1.2 billion people teach geriatrics. And less than 15% of the population is covered by a pension system, which offers as little as $1.50 a month.
Kerala is at the leading edge of the trend, reportedly home at one point to half of India's senior-care facilities. The state is among India's most rapidly aging, its average life expectancy, at 72, nearly six years above the national average. And it has one of the highest percentages of its labor force working overseas.
Although there are growing options for middle-class retirees, those at the bottom in India often fall through the cracks. Institutions such as the 20-bed Bethany Home for the Aged, on the outskirts of Trivandrum, struggle to cope, taking in those destitute, abandoned, afflicted withAlzheimer's disease.
