A former colleague is on his way to Kenya to work for 3 weeks in an AIDS clinic. Carl is a geneticist, sailing enthusiast, and horse riding nut! Overall a good man...and he is doing wonderful things in his retirement - to tell you the truth, if I'd known about this trip - I would have gone with him. We worked together for years on AIDS diagnostics testing, developing a very cheap but very accurate test that is still being used in certain countries in Africa to this day.
