About My Challenge
Retired astronaut. Current geologist. Apparently going from spacewalks to push-ups was the logical career progression.
I’m knocking out 3,307 push-ups in 24 days for Push For Better to raise funds for mental health in Australia. Turns out gravity is much less forgiving down here.
