| demanding. What you're describing is cleverness, and it's a

| Even some of your examples I'm not convinced are lazy

| switch at ankle level with my toes if I can do it well
| enough, when bending down would take so much more effort? I
| think by your standard I should be commended for my foot
| dexterity! When does the desire to reduce effort cease to be
| vicious and become virtuous?

| Edit: Sorry, I think maybe you are asking why HN doesn't

|
| Yes. The system here normally seems to check uniqueness.
