You are going to have a great life! But as George says, with a better inner awareness. You will find that you have a better appreciation of things that many people just take for granted, and can prioritise the important things in your life better than you did before.You will probably suffer fools lightly (hence your remarks about stupid/typical 20s things), but don·t be too hard on them, enjoy life, do lots of things that take your mind off the c word, and never miss a check-up.
