Sky,
I heard that same number, "7" years, I am starting feel that is so true, but you have to "live" a lot of years to see, feel, the differenace, eh? 48yrs for me, is enough to convince me "science" is right. . . again.
Now, I ask myself, the sags and bulges, where will they be in the next 7? Bigger, smaller, or will I not be here to know the answer. ha!ha!
That's me.
