My dad is very ill

Just as a head's up for anyone who knows and likes my dad, or wonders why I will be distracted for a while here, my dad has been ill lately. Went to the doctor yesterday for an exam, and after a chest x-ray he's immediately admitted to the hospital. Further scans indicate large stage 4 tumors in the lungs and brain. Biopsies to come, but anything that is in multiple areas has metastasized, so is inherently malignant. No numbers have been put forward, but its very bad and timescales may be very short. And, if anyone wonders, he never smoked a day in his life, worked in a factory or... anything that would be a risk factor. If anything, much more active than the norm.
