Good Guy and Larry Wall gave really great responses to your question. I too am over 60 and I know from my own experience that life takes on a totally different perspective with age.
When I was younger so many things seemed monumental in importance and scope and consequently a lot of energy was spent focusing on the superficial rather than things that really matter in life.I have now reached a point where I simply take things with an easier, softer approach. Although we cannot totally remove stress, we can remove many of the conditions that cause it. For instance, I do not use an answering machine on my land line phone or on my cell phone. My philosophy is that if a call is important, then the caller will phone back.
I don't try, rather I do live now with an attitude of gratitude! Jealousy, envy and even anger have taken a backseat to appreciation, jokes, smiles and love of family and friends.
I attempt to mentor the younger crowd to not get all jammed up with how clean the house is, whether their lawns are perfectly manicured, if they are taking the best vacation ever or a myriad of other pressures of life. Instead, I tell them, "Don't sweat the small stuff because when we are on our death beds, it is all small stuff."
