Shared medical misfortunes

While studying a postgraduate course in health psychology, I started to become friendly with another student on the same course. On further acquaintance, it turned out that she too had survived Hodgkin's disease (Lymphoma) about 15 years previously and had also suffered the tragedy of having a stillborn baby (no know causes) born on 10th June (although not in the same year). I believe that the odds of getting Hodgkin's disease in the general population are about 1:40,000 and stillbirths were probably about 4.5 per 1,000 in 1988 plus the date coincidence. We lived about 20 miles apart so presumably have no particular shared environment as causal factors. One of us had the stillborn baby before cancer treatment and one years afterwards. Added to that we have both undertaken first degrees in psychology as adults and then landed up in this new postgraduate masters course together. Furthermore we had become friendly enough to discuss these difficult topics. The good news is that we have remained great friends for over 22 years already!
