You can save someone's life.  Please, register to become a potential bone marrow donor.  Before the transplant, the doctors told us that we'd be lucky if Jacob lived until he was 10.  His bone marrow transplant changed everything:  we just celebrated his 6th birthday and he's going to Kindergarten this fall.  It's a real-life miracle.  His donor, a kind woman we've never even met, has given him each and every one of these days, each and every one of these years, each and every one of these opportunities.  She saved his life, gave him the opportunity for a full life.  Joining the registry will cost you $52.00 and 30 minutes.  You can complete the process through the mail.  The link below will give you all of the information you need.  I promise you, it's worth it.
