Imagine you had a real labour intensive job, rather than our soft, easy, cushy 'jobs'...
Imagine digging fence post holes all day, trenches, laying bricks, anything else really!
Wow what a pathetic, meek, frail society we have become where people wing about how hard it is to sit on your ass all day long!
Edit: I guess I should add... sure I can understand mental fatigue; sometimes we work with mind numbing, brain twisting complexities. But that just means you should go make a coffee, go for a 15 min walk by the river, whatever. But physically, if you're saying 'computing' is hard... surly this is a joke/troll ... !?
