Getting back a pilot Licence

I have flown since I was 25 years old, and now I am 70. I became a commercial pilot and added aerial work (Cropdusting). I flew in Colombia, and a couple of incidents/accidents made me give up flying crop-dusting. I immigrated to the US in 1985 where I flew from 1996 to 2002 when I stopped flying(life happens). Life is happening again and now I am determined to fly again as a pilot in command, the journey has been complicated but that is how life is. It is all about living life to the best of our ability,
