I feel you, i worry about it too even though i still have my balls and just taking anti-androgens to simulate castration, pretty bad on my liver but maybe i can still have children of my own one day, or maybe i will die of liver failure before i turn 40, and if that were the case better to live 40 years and enjoy all that i can and have hair, than to live into old age, sad, depressed and always living in constant mental agony and resenting life. But like you said yolo, in the big picture nothing matters. Were just some animals on a rock in space among Infiniti galaxies full of other animals on other rocks in space, nothing really matters in the end. We're here and self aware for a short time so do all that you can to enjoy it.
