Is it different? Yes, it is. Everything is different. Do I get tired? You bet I do. Much more than before, but I know this is temporary. And, while much of the rest of me may be suffering... my knees are not the problem!

(Sorry OP that we've gone a bit off topic. I just want to reassure people with bionic parts that that travel is still possible, at least from my recent experience.)
