Walking through the hall today, a colleague casually introduced me to Mike Barratt. That would be the same Mike Barratt who was the lead crew surgeon for the International Space Station and more recently spent 199 days in space as a NASA Mission Specialist.
Chatting with him on the elevator, he mentioned his five children, ranging in age from 9 to 23. He also gave me the best quote of the day: "Space flight is easy. Raising children...now that's hard."
