Greetings,
Congrats, and like my brothers said it is never too late, and you are never too old. Regardless to what the age of a man, you are not in dotage, until you feel you in dotage. If you are able to do degree work and you are 85 years old, then so be it. There is a point in a man's life when he need to be brought to li/G\t and that time is now for you. Best of wishes in your travels. . .
