A few more suttas and teachings on Aging:

Sn 4.6 Jara Sutta On Decay
Translated from the Pali by John D. Ireland
"Short indeed is this life, this side of a hundred years one dies; whoever lives long even he dies from old age. People grieve for things they are attached to, yet there exist no permanent possessions but just a state of (constant) separation. Seeing this one should no longer live the household life. That which a man imagines to be his will disappear at death. Knowing this a wise man will have no attachment (to anything).
"As a man awakened from sleep no longer sees what happened in his dream, similarly one does not see a loved one who is dead. Those people who were seen and heard and called by their names as such and such, only their names remain when they have passed away. Those greedy for objects of attachment do not abandon sorrow, grief and avarice, but sages having got rid of possessions, live perceiving security. For a bhikkhu with a detached mind, living in a secluded dwelling, it is right, they say, that he no longer shows himself in the abodes (of existence).1
"A sage who is completely independent does not make close friends or enemies. In him sorrow and selfishness do not stay, like water on a lotus leaf. As a lotus is not wetted by water, so a sage is not affected by what is seen or heard, nor by what is perceived by the other senses. A wise man is not deluded by what is perceived by the senses. He does not expect purity by any other way.2 He is neither pleased nor is he repelled (by the six sense-objects)."Notes
1. There is a play on words here: "bhavana," besides meaning "an abode of existence" also means "a house." So as well as saying, he is not reborn into any realm of existence, the passage also indicates he lives secluded and does not associate with people in the village.
2. By any way other than the Noble Eightfold Path (Comy).http://www.accesstoinsight.org/tipitaka ... .irel.htmlFrom Discourses
On one occasion Buddha sat warming his back in the western sun. Then Ananda went to the him and massaged his limbs with his hand and said, "It is amazing, lord. It is astounding, how the Blessed One's complexion is no longer so clear and bright; his limbs are flabby and wrinkled; his back, bent forward; there's a discernible change in his faculties - the faculty of the eye, the faculty of the ear, the faculty of the nose, the faculty of the tongue, the faculty of the body."
"That is the way it is, Ananda. When young, one is subject to aging; when healthy, subject to illness; when alive, subject to death. The complexion is no longer so clear and bright; the limbs are flabby and wrinkled; the back, bent forward; there is a discernible change in the faculties - the faculty of the eye, the faculty of the ear, the faculty of the nose, the faculty of the tongue, the faculty of the body."
"Those who live to a hundred are all headed to an end in death."
[From SN 48.41, Jara Sutta - Old Age]
The aging of beings, their old age, brokenness of teeth, grayness of hair, wrinkling of skin, decline of life, weakness of faculties - this is called aging. With the arising of birth there is the arising of aging and death.
[From MN 9, Sammaditthi Sutta, v. 21-22 - The Discourse on Right View]
The householder Nakulapita went to the Blessed One and said, "Bhagavan, I am a feeble old man, aged, advanced in years, having come to the last stage of life. I am afflicted in body and ailing with every moment. And it is only rarely that I get to see the Bhagavan and the monks who nourish the heart. May the Bhagavan teach me, may the Bhagavan instruct me, for my long-term benefit and happiness."
"So it is, householder. The body is afflicted, weak, and encumbered. So you should train yourself: 'Even though I may be afflicted in body, my mind will be unafflicted.' That is how you should train yourself."
Sariputta added: "And how is one afflicted in body but unafflicted in mind? A well-instructed disciple has regard for noble ones and is well-versed and disciplined in their Dharma; has regard for men of integrity and is well-versed and disciplined in their Dharma - his form changes and alters, but he does not fall into sorrow, lamentation, pain, distress, or despair over its change and alteration."
[Excerpts from SN 22.1, Nakulapita Sutta.]
On one occasion two brahmans - feeble old men, aged, advanced in years, having come to the last stage of life, 120 years old - went to Buddha and said to him: "Master Gotama, we are brahmans - feeble old men, aged, advanced in years, having come to the last stage of life, 120 years old. Teach us, Master Gautama. Instruct us, Master Gautama, for our long-term benefit and happiness."
"This world is swept away by aging, by illness, by death.
For one swept on by aging no shelters exist.
Keeping sight of this danger in death, do meritorious deeds that bring bliss.
Make merit while alive.
When the world is on fire with aging and death, one should salvage [future wealth] by giving:"
[From AN 3.51 and 52, Dvejana Sutta - Two People 1 and 2]
How can aging and the signs of aging be used as a spiritual practice? Mostly, I don't want to see them - so that is just dosa.
