Why is that when I was young I had such a terrible time with my skin, constantly hiding my face due to pimples and now that I am older my skin is so clear?  Why is it that I struggle so with my weight now that I am older but took for granted the slim figure that was effortlessly maintained in my youth?  I can grow long nails now in my older years but struggled with biting my nails as a teen.  What virtue do I have now that I will wish for as I grow older?
