Los Angeles: Oscar-winning star Denzel Washington says that the secret to his 35-years of married life is that he keeps his mouth shut and follows instructions.

Three and a half decades into his marriage, Washington has learned a few things about what makes his lasting love with wife Pauletta work.

‘I do what I’m told. I keep my mouth shut,’ Washington, 63, joked to people.com.

The ‘Equalizer 2’ star also revealed that when he and his wife celebrated their 35th wedding anniversary in June, they did so in a low-key way.

‘We just chilled, had some dinner. It was kind of quiet,’ he said.

So what is their secret? What makes a marriage work for three decades?

‘There’s too many things!’ said Washington of what he appreciates most about his better half.

‘What pops into my head: security, food, a beautiful home. The difference between a house and a home, it’s a big difference. You can buy a house, but that doesn’t make it a home - and not to say a man can’t make a home a home, but my wife has made our house a home, and raised these beautiful kids (John David, 33, Katia, 30, twins Olivia and Malcolm, 27) and protected them and sacrificed for them, she did the heavy-lifting,’ he added.
