Tim encountered an 80-year-old man on the beach who was moving with incredible speed and determination using a walker. Despite his age, the man exuded vitality (he did not let the old man in). This is a reminder that age is just a number, everything is relative, and our mindset and attitude towards life matter more than the years we've lived. Tim's conversations with the 80-year-old in Florida and the 40-year-old black belt underscore the idea that our mindset shapes our experience of life.
