How long does Chronic fatigue syndrome last?

No, you cannot die from CFS. IT can cause depression and is very dificult to deal with but is not deadly. The problem is properly diagnosing the cause of CFS. According to the book 'America's Biggest Cover-Up: 50 More Things Everyone Should Know About The Chronic Fatigue Syndrome Epidemic And Its Link To AIDS', in 1993, a leading CFS researcher, Dr Paul Cheney reported that five of his twenty CFS patients died in that year- two committed suicide and three, like AIDS patients, succumbed to overwhelming infections that their damaged immune systems just couldn't fight off. There is much speculation that CFS patients may have similar immune system deficiencies as so-termed 'non-HIV AIDS' cases.


Which has the smallest diameter squamous epithelium red blood cells smooth muscle cells or sperm?

== == I do not know about epithelial cells but i do know this: Red blood cells are the smallest ones measuring about 6 or 7 um. Sperm cells are also very small(25um) but are big compared to red blood cells. Its dificult to compare these cells to muscle cells because they are long but skinny. ________________________________________ (New to this answers thing, don't feel comfortable deleting other people's stuff) I just did a bio lab and these are my measurements: Red blood cells: 8µm wide; 10µm long Sperm cells: 2µmwide; 10µm long (known to vary) Striated muscle (This is skeletal muscle, like a bicep; I don't know how it compares to smooth muscle and they really varied in length) 40µm wide; 430µm long Cheek epithelial cells: 59µm wide; 63µm long
