Diet, exercise and hygiene
If only it was that simple.
I (did) cycle regularly.
I played golf twice a week.
We enjoyed walking.
I loved my veg and salad....and fruit.
But when flu decides to give you a kick in the nuts all that counts for nothing.
I got 'real' flu** in the 80s when I was really fit and ate well........it wiped me out and I was off work for 3 months.
**I was unconscious/delirious but apparently the doctor at first diagnosed meningitis.
This flu, Dec-March was not as severe but the after affects are crippling.
