Lost knowledge

Today I had my dad help me look at Randy’ brakes on his car. While working the thought crossed my mind that once my dad goes, I will lose a lot of knowledge that he has about cars. Also, in our neighborhood we have a lot of older couples that have had experience. Several served in WWII, many things they will not talk about. Some went through the depression as well as a lot of hard time, yet they got through it. Once this great generation leaves us we will lose a lot of experience and knowledge. For that I am sad.
