People who criticize the current age gap difference between actor and actresses, shouldn't forget that 70s, 80s, 90s was the hay day of not only age gap, but marriages between co actors.
Dimple Kapadia was 16 when, Rajesh Khanna who was 31 and a well established superstar, married each other.
Divya Bharti also, was 18 when she married sajid nadiadwala who was a producer.
People got the concept of nepotism after 2017-18, but it became a nationwide topic in 2020 after Sushant's death. But you shouldn't forget that nepotism have existed since forever. Just like this, age gap was also a even more problematic issue in 80s , 90s.
Even during saif ali Khan's first marriage when he was 20, kareena kapoor had attended the function as she was 10. And in 2010 they started dating and married in 2012.
To say age is just a number, is a fallacy.
Even if two 16 years old individuals are marrying eachother, that's still acceptable than have a 35 year man marrying a 16 or 18 year old. Age matters.
Still, there are some exceptions like jay mehta and juhi chawla.
People today troll juhi for marrying a rich guy, as they don't understand that they actually had a pretty normal relationship before marriage and even after they married, jay mehta was okay with not announcing it as it could have affected juhi's career.
