Labradors are a large breed, but they live longer than many dogs their size. They tend to stay playful well into middle age, which can hide the early signs of stiff joints, so watch for slowing down on walks or reluctance to jump into the car.
A 5-year-old Labrador is about 40 in human years, and a 10-year-old is about 66.
In a 2024 study led by Dogs Trust, published in Scientific Reports, which looked at more than half a million UK dogs, half of Labradors lived to 13.1 or older. That's longer than dogs overall, and about the same as a person reaching 83.

Labradors count as large dogs (23 to 41kg when fully grown). Large dogs age a little faster than smaller ones: after two, each year adds about 5 to 6 human years. If yours is much lighter or heavier than usual, pick their actual size in the full converter.
