I donate lots to charity. I don't necessarily tell everybody the number or what I do.

I'm going with the flow. I feel when the time is right to stop, it will be flashing in neon lights for me, like this is it. It could be this year, it could be next year, I have no idea. Anyone in their profession seems to think it's fairly clear when it's the right time. I haven't had that moment of clarity.

I don't enjoy being in Europe for weeks on end, so I just skip it.
