• "Mere 47,xxy wouldn't explain the stuff going on in my endochrine system, especially with the bizarre Cholesterol levels."
• "Perhaps this explains why Kleinfelter males, those with 47,xxy chromosomes rather than the usual 46,xy, between 1 in 500 and 1 in 1000 of the general population are over-represented in the IT industry."
