The answer would depend upon a few other factors, such as any health or mental complications that would occur as a result of such a change.
If I have nothing to object to along along those lines, then I would indeed agree to it with little hesitation. An inevitable march to the grave never particularly appealed to me. I do desire an end to life, but wish it to occur in a manner and time of my choosing, rather than simply decaying to the point where my life is a mockery of what it once was.
I enjoy kids, love being around them, love teaching and caring for them. I do not however particularly care if they are mine or not, and to be frank do not particularly desire the responsibility of caring for them on a permanent basis. The life of a perpetual grand uncle to the descendents of my siblings is far more appealing to me than dealing with a brood of my own.
