My sister died at 21. She had a sharp pain in the side but took some antacid and didnt go to the doctor. If she had, that doctor would undoubtedly have heard the pulsating noice from the aneurysm on her spleen artery that noone knew about, about to burst.
Being the engineer I am I always want people to go to the doctor to have things checked and fixed.
Your Heather did some beautiful things.
