To save you a little typing and make your code slightly clearer you can take advantage of the fact that variables interpolate inside double-quoted strings. So, instead of

print $fileAgeInDays, " days since it was created\n\n";
[download]

you can do

print "$fileAgeInDays days since it was created\n\n";
[download]

Note that interpolation does not occur inside single-quoted strings.

I hope this is of use to you.
