MEERUT: Karan Singh’s parents were a worried duo when he started school. He was to enter kindergarten, but was already five feet tall.

“When he started school, kids would run away from him. With time, the kids got used to him and now he has many friends,” says Sanjay Singh, Karan’s father. Karan holds the Guinness World Records for being the tallest for his age — in a few months, he will turn six years of age and he stands 5 feet 7 inches tall. He’s not alone though. His 25-year-old mother, Shweatlana Singh, is 7 feet 2 inches tall. What’s more, the family claims she is still growing — at about four inches every two years. Until 2012, she held the Guinness record for being India’s tallest woman. Siddiqa Parveen, from West Bengal, at 8 feet and 2 inches, replaced her.Sanjay, a dietician, recalls that he fell in love with her in a Bangalore college. They married in 2007. At 6 feet 6 inches, he says, “Both of us are perfect for each other.”Meerut-based Harish Mohan Rastogi, a doctor who has studied human growth, says it was hard to imagine that at 25, Shweatlana continued to grow. “Epiphysis, the process that aids the growth of bones, ends by about 21 years of age. In some cases, because of excessive release of a growth hormone, a person’s height might increase up till the age of 25,” he said. Interestingly, the mother and son are also blessed with an acute sense of hearing. “They can hear sounds from far away,” Sanjay claims.
