Where does this formula come from?

Scientists from UC San Diego (2020) studied DNA from 104 Labrador Retrievers and discovered: dogs don't age linearly! They age rapidly early in life, then slow down.

Forget the "multiply by 7" rule — it's a myth.

H=16ln(D)+31H = 16 \cdot \ln(D) + 31

H — human age, D — dog age, ln — natural logarithm

Examples:

  • 1 year → 31 years
  • 2 years → 42 years
  • 5 years → 57 years
  • 12 years → 70 years
