= John's age (in years)
= Jack's age (in years),

Jack uses the phrase "when I was your age," implying that ,
but we know that the difference in ages is years.
So, years ago, Jack was Jon's age, and
John was years younger than he is now, so his age was
.

<---><---> .
Jack says "when you are my age, our ages together will be 63."
That is in the future, years into the future,
since that is the difference in their ages.
At that point,
John's age will be (Jack's current age), and
Jack's age will be
.
The sum of their ages at that point will be
<---> .
