My young mother turned 69 a week ago today. I flew down to Arizona to join my sister in celebrating her birthday together. I got clocked at Scrabble (my younger sister won) and had fun reminiscing with our mother about old times when we all lived under the same roof with our hip Mommy and Daddy in the 60's and 70's.
I look at these two humans, from whom I gained my genetic material, and I think very hard about nurture vs. nature. My sister and I have always experienced very different medical developments, in spite of our shared genetic heritage. Much of our mother's afflictions are attributable to lifestyle choices. Our father's challenges seem to be more hereditary.
