Where can one learn about giving care to the elderly?

There are qualifications you can receive in colleges that teach you how to nurse for the elderly, however you do not have to go down such a formal route if you do not wish to. Elderly care homes will often offer free guidance if you ask to volunteer there since such places are frequently under-staffed. You could also peruse the internet to find out how to care for the elderly or look into your local library for relevant books.
