There are loads of things we're told to do to stay healthy and youthful - usually revolving around getting lots of exercise, eating your five-a-day and not drinking too much.
But one 100-year-old woman reckons it doesn't have to be quite so militant, having said she's a massive fan of Stella Artois lager. Oh, and custard creams.
Eileen Maher, who was born in Darwen, Lancashire, celebrated her 100th birthday recently with her pals and staff at the care home in Blackpool where she lives.
The former mill worker even proved to be the life and soul of the party, seen posing for her first selfie while enjoying a special concert and a dance with fellow resident John Simms - who donned his ENSA (Entertainments National Service Association) uniform in her honour.
Eileen didn't have any plans to celebrate her milestone birthday, but staff at the Princess Alexandra care home had different ideas.
Elaine Wright, care services manager, said: "Eileen said she just wanted her telegram from the Queen - and to be loved."
She also added the special secret to why Eileen's looking so good at 100, saying: "Eileen's not big on bubbly so her favourite tipple was on tap - Stella Artois!
"With a packet of custard creams, it's her not-so-secret self-indulgence."
As well as receiving her special message from the Queen, Eileen was also surprised with a special visit from friends Tom and Pauline Green, who are like family to her and travelled over 250 miles from Surrey to be with her.
Pauline said: "Eileen was my mother's best friend.
"They went on holidays, even the Queen Elizabeth 2 (QE2), together.
"I see her as my auntie, she's a wonderful woman."
Eileen - who never had any children and only moved to the care home three years ago following her husband Frank's death - said she was 'made-up' with the celebrations.
She said: "It's all been wonderful.
"I didn't expect a party but it's lovely they have done something so special for me. Being content has helped me reach my 100th birthday."
Explaining her and Frank's love story, Eileen said: "My friend told me to go to a local hotel as there was a man who was a fantastic pianist.
"It turned out to be Frank and I went and fell in love with him - he was a great jazz pianist.
"We married in 1951 when I was 33.
"We came to Blackpool for our honeymoon and never left.
"We used to love to play tennis too but now I just enjoy listening to it as my eyes aren't as good as they used to be."
Happy birthday, Eileen - we'll be raising a can of Stella to you!
