I'm 38, my dad is 71. We almost lost him last June, but he had an emergency quadruple bypass and recovery was slow, but smooth. The doctors said if he had gone into full cardiac arrest they wouldn't have been able to save him, even if it had happened on the operating table. Not a day goes by that I don't call him and my mom to tell them I love them. Funny thing is, I can't remember saying it prior... I know I did, but not nearly often enough. All I can say is, tell your loved ones that you love them often, I got a second chance to say it to my pop, but sometimes in life you don't get that lucky.
