I was reading an article o n heroines who lead a lonely life and in it, it says that Sadhana (the actress from the 60's, her movies include Hum Dono, Mera Saaya and so on) died in 2004 at the age 75. I always assumed that she was alive and well. I have never read this anywhere else, it doesn't even say it on Wikipedia. So if anyone knows for sure pls. do tell!
