I think that has a ton to do with it. The Grandfather in this picture was the most peaceful and wise person you will ever meet. He was married to my Grandma for over 70 years and my Dad and my 2 Uncles all say they never saw them argue. He also used to be really grateful of nature and his surroundings and really compassionate and helpful to every one he met. My other Grandpa lived in the clouds and was always happy, never saw him upset either.
