IF i have the same gene; but, we could grow a little older; but, the gene keeps on regenerating back; pros and cons. My son's classmates; and now fellow Collegiates said, "Really, your mom; can't fool us man; that is your sister! Maybe your mom died long ago; and she did not tell you?" Yacht! And, we actually had a serious talk...confirming that I am the mom. / From that day on; I wish never to take off my gray hair ever. Not so many; but, some has this gene.
