Fifty? Pfft, sure! I'm almost there, and yes, I want to continue… Now Sixty… I'll confess that my evil "plan" from many moons ago was to—by then—be able to balance this with my other loves, being outside and moving (not just my fingers). I suppose many professions suffer from the same disadvantage, but programming is a slow killer. Eyes, joints, all that clot-inducing sitting, disrupted cicardian-rhythms, too easy to get trapped in bubbles disconnected from reality, you need to be extra-vigilant and pro-active if you care at all about your health and those that love or at least put up with you.
