The ergonomics experts can shove their fancy diagrams where the sun doesn't shine. After 15 years of hunching over code, I've evolved to my final form: laptop on chest, controller in hand, neck at an impossible angle that would make a chiropractor cry. Sure, my spine resembles a question mark now, but at least I can debug that production issue while horizontal. The real senior developer posture isn't standing desks—it's whatever position lets you code without getting out of bed. Work-life balance achieved.
