So much for the space, he emailed me when he got to work to let me know that one of his coworkers died this morning. He was the same age as my H. I didn't know him so he said the reason he was telling me was, it was an allergy related death and my S15 just developed seasonal allergies. I did respond with an I'm sorry for your loss email, and will keep an eye on S15. I wasn't sure what to do and I was sobbing at the moment, so possibly I shouldn't have responded at all.
