LOL, yes chasing kids down is exercise :).
Perhaps you should try the anti-anxiety medication at bedtime and see if it does not reduce the hearting pounding in your ears problem.
I will have times when I am feeling anxious and lying in bed when I can hear my heart pounding so often just changing positions will help me.
Another thing you may want to watch is your BP as hearing you heart pounding in you ear may be a sx of high blood pressure.
Just my 2 cents worth today.
