It is my observation that, in general, people tend to get better looking in appearance as they mature. This is true for both men and women through their 30s, 40s, and 50s. It is also true, I believe, for many people - but not all - even in their 60s. However, I would say that whatever level of improvement in appearance one attains in his or her looks by the late 50s inclines to become static in one's 60s.
But when you cross the threshold into your 7th decade, a dramatic shift occurs. Big changes in your appearance and in your body are starting, none of them for good. I remember that Jack Nicholson, a notorious sex symbol and confessed womanizer, once said, "I can't hit on women in public any more. I didn't decide this; it just doesn't feel right at my age. . . There were points in my life where I felt oddly irresistible to women. I’m not in that state now and that makes me sad.” 74 at the time, It had all changed. He experienced what I am talking about. Both he and countless women knew it.
It is sort of like flying on an aircraft at 30,000 feet at that level cruising speed when you notice immediately that instant when the plane shifts into a descent. You can feel it. You and everyone on the plane with you can even see it. The entire cabin is now tilted DOWN. You are coming in for that scheduled and inevitable landing. Your flight will soon be over.
Now what I have described was put much more succinctly by a man named Moses when he wrote Psalm 90:10 in the Bible about 3500 years ago that goes like this:
"The years of our life are seventy, or even by reason of strength eighty; yet their span is but toil and trouble; they are soon gone, and we fly away."
