Head in Hands

From time to time I've been gripped by a strange phenomenon. When resting my head back into a cupped hand, I've had a disconcerting feeling that either my hand is very large or my head is very small. In reality, I think neither is the case, but I clearly have a disproportionate opinion of their relative sizes. My hand simply does not seem large enough to cradle the bulk of my head. Nor should my head be small enough to sit neatly inside my hand. I wonder if Jeremy Beadle ever had this problem.
