When I had finished reading the book," A Whole New Mind" I was challenged to think of what my life would be like when I reached 90 years old. I see myself as a successful engineer and at that point I know that I will be retired. I also visualize myself owning a home in Paris living with my wife and having the grandchildren surrounding me. I envision myself as having made contributions to the Invisible Children foundation throughout my life but hope by the time that I reach 90 there will be no more famine in Africa. I also see myself as having travelled and performed humanitarian type works and even continuing to do so at 90. I predict that my biggest regret will be that I haven't enjoyed life enough, because I tend to rush through life now. The fact that I have made it to 90 is amazing, although I suspect the average life span may be in the 80s. Even so, I must have lived decently and will hopefully be in good health to enjoy my retirement and to be able to give back to the world in a positive fashion.
