That's big PHEW Moonlight
you had me worried there, ....you look after yourself, the older we get the less punishment we can take, and we're even less invincible than we thought.
FWIW In the winter 2002-03, At 75 YO, My reasonably fit still working part time (Plumber & Heating Engineer) late father caught a cold, ....and in the middle of said cold the obstinate old fool (I'm being polite .....there was a lot of family crap between us !)
..much against Mother's wishes went out to change a boiler.
2 days in cold house in cold damp weather etc etc turned his cold to pneumonia, a week later he was in Intensive care for 10 days, ..... followed by another 3 weeks in High Dependancy, followed by another 14 days in general hospital.
That dose of pneumonia broke him,........despite everyone's best efforts he ''gave up and took to his chair'' - becoming an ever bigger and more embittered PITA ........and died 3 days before Christmas 2009, not seeing the arrival of his first great grandchild.
Okay, the above may be an extreme case, .....but IMHO, catching preventable diseases etc etc is at the very least, being very unfair to those who have to look after you.
