I would take each of your sentences and make a little list
of the things you think it might be saying. Make sure not to just summarize or restate
what it is saying. In making your list of ideas, think of how you would finish these two
sentence starters:

• This quote
  shows...


• This quote is important
  because...

In looking at your first quote, I
might have a list that looks like this:

• Man must
  thrive on human interaction.


• The stage in life wherein
  that interaction has potential to drop is in elderly years, after
  retirement.


• Lack of interaction cripples the elderly
  possibly more than disease or faulty muscle tone.


• Living
  alone deteriorates one's social ability


• Potential
  struggles may be depression, anxiety, and fear.


• Getting
  lost in their own mind may even be one of their
  struggles.

After looking at all the ideas I am
capable of generating, I mix up about 3 of them in one sentence to make myself sound
intelligent and show some interpretation of the quote I am
using.

You try with your second
quote.
