Walking briskly indicates good health.
Mayo Clinic Proceedings from June 2019 article states walking slow, steady or briskly can actually predict how long a person can live with shorter life expectancy.
A Female normally walking slow is expected to live in between 72 to 85 years, whereas, a female walking briskly is expected to live to 87 or 88 years of age, for slow walker men their expected lifespan is in between 65 to 81 years, while the fast walkers expected lifespan is 85 to 87 years.
The average walking speed is 4km/hr or less which is considered to be slow pace, and that of 6km/hr or above is fast.
