You call us a successful design? Strewth mate! Wait till your my age and suffer the aches and pains I have. If we are so well designed why do we have a structure, the spine, which was originally a bridge but is now a column? It's a real pain in the neck ... lower back and thorax. To me that single trait shows that evolution does not necessarily produce an optimal design AND disproves intelligent design. And don't even start me on why males have sensitive reproductive organs on the outside. We all know where that's a pain.
