Jenny, a dear friend and mother of 4 amazing children that I love like nieces and nephews, once told me that hugs were crucial for a happy, stimulating, and rewarding life. I wholeheartedly believe this. I did a little digging, and believe Jenny's belief stems from this quote:
"We need 4 hugs a day for survival. We need 8 hugs a day for maintenance. We need 12 hugs a day for growth."
