Furthermore, think about this…sperm go 4mm/minute or 240mm/hour. 55 microns is , so sperm travel at 240mm/ = 4,364 times their length in one hour. Take a 6ft human. Multiply that by 4364, and you get 26,184ft/hour. 5,280 ft/mile, so 26,184/5280 = ~. Given that the average person swims about 2mph while Michael Phelps record speed is about 6mph*, sperm can be thought to swim (relative to body size) about as fast as the world’s fastest human swimmers, but certainly nowhere near as fast as the fastest fish, the sailfish, which can reach speeds of 68mph.
Yeah, because government solution ALWAYS work. I am a 12 year general education teacher who is overloaded with classes full of special ed kids. Many of these kids can be successful in the class, but other cannot and administration does a disservice to all parties involved by shoe-horning kids who belong in a small, more individualized class setting into general education classes. The majority of my gen ed kids are not getting the education they deserve because of the behavior challenges of some of the special ed kids. I am told I have to deal with it. In this case, the failure starts at the top and trickles down to the bottom where people such as myself are left to deal with inability or unwillingness of the “leaders” to properly address the problem and place ALL students in a setting that is appropriate for them.
Certainly Ivhu. So long as all the non-whites in my country (4 million of them in the UK) go home too. Don’t be daft. This is the 21st century and the future of the world is one in which we mix up more and more until there isn’t much difference between us. I don’t dislike Mugabe because he humiliated white people (they have dished out plenty of humiliation and had it coming) but because he has wrecked the future of an entire generation. When you say ‘We’ please speak for yourself. If you think that success is defined by the world’s highest HIV prevalence, massive unemployment, a collapsed currency and decaying infrastructure then Zim is probably the most successful country in Africa, apart from Somalia. And I have been all over Zimbabwe, assisting in the delivery of food aid and things are better than they were 5 years ago, but still dire. If you want to see a country that does it right, go to Rwanda, or even Tanzania. But not Zim. It’s a mess and it didn’t need to happen.
