It's raining today on the "wet" coast of British Columbia. But we certainly need this rain after the long, hot, dry summer of 2017.
My thoughts are turning back in time to Victorian days this morning (well, I am writing an historical novel after all). In 19th century England people did not expect to live long lives—average age was about 40! This figure was mostly because many infants and children died of disease and malnutrition.
If, however, you managed to survive to adulthood, you could perhaps live to the grand old age of 50, 60 or even 70. We have adopted that "three score and ten" notion today but, luckily, because of vast improvements in sanitation, nutrition and medical care, we can expect to go far beyond into our 80s, 90s, and even 100s.
