At 73 I am trying to keep up, this world is moving so fast, it is important to find new friends that understand more about new innovating concepts that can enlighten one on how things work such as crypto currency as one small example. Old friends often times are just negative about new and upcoming advances and get on board slowly. Computers, internet, emails and cell phones are examples, but those open to new innovations made the most of them. Kudos to you for listening and respecting your fathers incites and Kudos to him for staying on top of life. Love
