This may be construed as being a TAAT but its actually about several I've seen over the years.
The thread usually goes 'I feel so ill etc'
To which invariably you get 'well if you are on MN you can't be that ill' 
I'm lying down right now gently moving my thumb over the keys. Its not that demanding. OK I'm not ill but a few years ago I posted here saying my doctor wasn't taking me seriously when I felt so ill and yes within about 3 replies I had the standard that I wasn't unwell if I could type (move thumb) I had pneumonia it transpired. I wish some people would cut some slack.
