1) When I'm standing up (or walking) for a long period of time, I feel a little ache at my lower back. Not excruciating though, just mild. I'm curious cuz I'm standing up straight, so why?
2) Why is it that when I see myself walking with reelection of me beside me, it's like I'm not standing up straight, but I feel and believe I am standing straight? Like my head is leaning forward, when I feel that it's not.
3) When I sit on something without something to support my back, I tend to curve my back. Cuz when it's straight, after some time I'll feel tired and return to curving it. I dunno maybe it's tiring to carry my upper body weight? so I curve it?
