I was reading the following article about the strong motivating power of feeling regretful:

It made me wonder - older donors are already the cornerstone of individual giving. If we asked them "do you wish you had made more of a difference to the world with your life?" (in effect) - and then offered them the opportunity to do that via supporting a charity - would they further increase their giving?
