Your body changes continuously whether you participate deliberately or not.

Your body will not stay the same over the next ten years, in any version of them. It is changing continuously, and your only real choice is whether you have any input into the direction. Doing nothing is not neutrality, it is simply letting the change happen along whatever line inactivity and time produce.

Since the change is happening either way, decide what you want a share in. Pick one capacity to influence deliberately and leave the rest. Participation does not require a whole new life, only a repeated small vote.
