This graph is a lie!!! While it is true that advanced age changes some things, caring is not one of them. Its just that there is more to love; more grandchildren, more friends and acquaintances. Even though you have more time to yourself (assuming that you did in fact retire), yet more people in your life means more to do. This did not originate with me, for read what the apostle Paul says...
The Book Philemon
1 Paul, a prisoner of Christ Jesus, and Timothy our brother, to Philemon, our beloved fellow worker, 2 to the beloved Apphia, to Archippus, our fellow soldier, and to the assembly in your house: 3 Grace to you and peace from God our Father and the Lord Jesus Christ.
4 I thank my God always, making mention of you in my prayers, 5 hearing of your love, and of the faith which you have toward the Lord Jesus, and toward all the saints; 6 that the fellowship of your faith may become effective, in the knowledge of every good thing which is in us in Christ Jesus. 7 For we have much joy and comfort in your love, because the hearts of the saints have been refreshed through you, brother.
8 Therefore, though I have all boldness in Christ to command you that which is appropriate, 9 yet for love’s sake I rather beg, being such a one as Paul, the aged, but also a prisoner of Jesus Christ. 10 I beg you for my child, whom I have become the father of in my chains, Onesimus, 11 who once was useless to you, but now is useful to you and to me. 12 I am sending him back. Therefore receive him, that is, my own heart, 13 whom I desired to keep with me, that on your behalf he might serve me in my chains for the Good News. 14 But I was willing to do nothing without your consent, that your goodness would not be as of necessity, but of free will. 15 For perhaps he was therefore separated from you for a while, that you would have him forever, 16 no longer as a slave, but more than a slave, a beloved brother, especially to me, but how much rather to you, both in the flesh and in the Lord.
17 If then you count me a partner, receive him as you would receive me. 18 But if he has wronged you at all, or owes you anything, put that to my account. 19 I, Paul, write this with my own hand: I will repay it (not to mention to you that you owe to me even your own self besides).

Onesimus was a runaway slave. This was a crime and punishable by death. However, he became a Christian and its obvious that Paul loved him. Loved him enough to assume the debt of whatever he had done BEFORE Onesimus had begun to follow Jesus. Paul's letter to Philemon (who was Onesimus' owner) is a touching statement about the depth of feeling an older person can possess. I am very happy to say that most everyone I know who is advanced in years cares about others. Years have a way of teaching us how to love... believe it, because its true.
