Dear Anonymous Donor,

This will be a short letter since we’re not permitted to share any personal details about ourselves, although I’d love to tell you all about myself, my family, and my work. It’s also one of the more – if not the most – important letters I’ve ever written. So I’ll keep it really short. 

I can’t tell you how much I appreciate the gift of life you’ve given me via your stem cell donation – and how much it has meant to my family and friends as well. Without a stem cell transplant, doctors estimated my life expectancy to be between 2.5 and 3.0 years. If my post-transplant recovery continues as it has to date, there’s no reason to believe I won’t be able to live another 20 years. 

You have saved someone’s life. What a wonderful way to give back to a universe that itself gave life to you! 

I hope that at the appropriate time we might be able to exchange more personal information and maybe even meet via videoconference. Until then, know that you have already made an extraordinarily positive impact on this world in which we live, which these days desperately needs all the positive impact we can muster.  

With the greatest respect, admiration, and appreciation,

Your Anonymous Recipient
