My 70th birthday is this week. I am not deeply religious (I was raised Episcopalian, which is Catholicism without the sin and with birth control), but I recall being told as a child that God promised us three Score and 10 years (70).
Given that my grandfathers died at 49 and 62, I was not optimistic.
Turns out 70 wasn’t exactly a promise. I am not a bible thumper in any sense, but found this an interesting rabbit hole.
The “promise” is in Psalm 90:10.
10 The days of our years are threescore years and ten; and if by reason of strength they be fourscore years, yet is their strength labor and sorrow; for it is soon cut off, and we fly away.
Elsewhere, however, the big guy promises 120 years:
When mankind had become corrupted in the period preceding the flood, God said: 'My spirit shall not abide in man for ever, for he is flesh; his days shall be a hundred and twenty years' (Gen. 6:3).
Not to mention the good book warns us that old age is not for wimps (this from an Internet site):
Our earthly bodies become weary as we age, and you may also notice aches or pains. Take comfort in knowing the Lord shall renew your strength, according to Isaiah 40:31.
Also: Then they'll soar on wings like eagles; they'll run and not grow weary; they'll walk and not grow tired.
I’d write more, but it’s time for my nap.
