help, please

Excellent job, Rose :))

I don’t like walking up and down the stairs.
If an escalator is nearby, I always use it.
I spend most of time doing in sedentary office work.
I usually work at mycomputer, and have meetings or discussions.
My body sometimes feels unusual if I sit down at a desk for three to four hours.
My legs feel weak and my shoulders feel stiff.
These days, I try to stand up at least once an hour and walk around.
When I go to and from work, I walk from home to my office, and it takes about twenty to thirty minutes. That helps me feel better.
