Knowledge is higher with experience

And sometimes lack of it means you're in good health.
My son knows how it feels to crash a car.  Have allergy reactions but no idea of Snotty noses so today when it's like a flood he asks kindly how he can get it out and how long it's gonna take.  You should have seen he's face when I said it could take days...
Last time he also had a sore throat and thought he was going to die.  For ones I could say,  it is *only * a cold.
Simplicity can be so enlightening in a time when so many complex happenings  occur :-)
