Chris Hadfield [PHOTOS]: Canadian Astronaut's Painful Return to Earth, Prematurely Aged

Astronaut Chris Hadfield returned to Earth this week after serving a few months as Commander of the International Space Station. During his time in space, Hadfield became somewhat of an Internet sensation, hosting a few social networking accounts and posting videos and other information while in space. But after his return home, the famous astronaut admits that he is suffering a lot of physical pain and feels prematurely aged now that he is back experiencing Earth's gravity.

"Without the constant pull-down of gravity, your body gets a whole new normal, and my body was quite happy living in space without gravity," the 53-year-old Commander said in a video conference call with Canadian reporters on Thursday, which was just three days after his return to Earth.

"Right after I landed I could feel the weight of my lips and tongue ... I hadn't realized that I had learned to talk with a weightless tongue," he said.

Hadfield explained that his is suffering from overall body soreness, especially in his neck and back since they now have to support his head after months of weightlessness.

"It feels like I played full-contact hockey, but it's getting better by the hour," the former International Space Station Commander said. "The subtle things and the big things are taking some re-adaptation to get used to and they are coming back one by one."

"For now, I'm still trying to stand up straight. I have to sit down in the shower so I don't faint and fall down, and I don't have calluses on the bottom of my feet yet, so I'm walking around like I walked on hot coals," he said.

"We're sort of tottering around like two old duffers in an old folks home," Hadfield said, referring to his crewmate who had also returned home, United States astronaut Tom Marshburn.

Hadfield along with Marshburn and Russian cosmonaut Roman Romanenko ended their tenure in space with a parachute descent of their Soyuz space capsule onto the steppes of Kazakhstan.

"We hit the Earth just like a car crash, like we expected," he said. "There was enough wind so that we rolled up on our side. I was the guy hanging from the ceiling. Our first true sense of being home was a window full of the dirt of the Earth and the smell of spring and the growing grasses in Kazakhstan wafting in through the open hatch."
