For those who want to hit one hundred and receive a letter from the queen, it might be worth taking a leaf out of 109-year-old Jessie Gallan's book.
Yes, you heard correctly.
Gallan, who is the oldest woman in Scotland, was born in a tiny, two bedroom farm cottage back in 1906. She had five sisters and a brother, who she shared a straw-filled mattress with to sleep on at night.
Aged 13, she left home to become a milkmaid. Later on in life she became a farm kitchen worker and then worked in a hotel.
Gallan, who now lives in a care home in Aberdeen, is still mobile (with the help of a frame) and attends exercise classes at the home regularly.
After celebrating her 109th birthday earlier in January, Gallan told the Daily Mail: "My secret to a long life has been staying away from men. They're just more trouble than they're worth.
"I also made sure that I got plenty of exercise, eat a nice warm bowl of porridge every morning and have never gotten married."
Well, that's that settled then. Sorry guys, but Gallan knows best.
