まっすぐ歩くようにしています

I've paid attention to how I walk usually in these days.
My posture isn't good, for instance, slightly stoop, and so on.
So, standing for a long time, I feel unusual feelings.
It's not so much as an ache, but standing still I feel tired.
When I suffer from it, I bend down on and off, and I try to direct my attention to other things.
I have been trying to attempt to retain the right posture, but it has been hard for me.
Although it doesn't mean being unable to do it.
Furthermore when I walk I attempt to have an image as if I walk on a straight road.
This is also hard though.
It's hard to hold own balance.
If anyone isn't around me, I want to open my both arms.
I don't know whether something will change for the good of these actions.
Anyway, I try to do these.
