Do you want to be smarter? More self-confident? Have a faster metabolism? Avoid wrinkles? With the discoveries of how methylation of DNA affects born-in traits, both physical and psychological, of animals and humans, we can hope for the day when this process can be controlled by the choices of the individual involved. Would require some sort of permission forms as the results, otherwise, could be quite horrifying. And the effects should be temporary, since otherwise one could choose a personality that refused other choices...

Sounds fascinating, but for us lay people, what exactly is "methylation of DNA"?

I believe the term you're looking for is Eugenics. Sir Francis Dalton beat you to the punch (by 130 years). Methylation of DNA is the binding of Methyl groups to DNA nucleotides. Basically its how gene expression and cell differentiation is regulated. Eugenics in theory could be an incredible leap in human evolution, but in practice its tainted like most theories by humans. In practice, a prime example of the use of Eugenics theories was the Holocaust.

methylation = attachment of a methyl group -- in genetics, to a protein or rna/dna.

epigenetics isn't eugenics:

epigenetics is the study of inherited changes in phenotype (appearance) or gene expression caused by mechanisms other than changes in the underlying DNA sequence, hence the name epi- (Greek: επί- over, above) -genetics. These changes may remain through cell divisions for the remainder of the cell's life and may also last for multiple generations. However, there is no change in the underlying DNA sequence of the organism;[1] instead, non-genetic factors cause the organism's genes to behave (or "express themselves") differently.[2]

Also, read the Oryx and Crake trilogy by Margaret Atwood, for an example of how genetic manipulation can get out of hand.

It's an awesome idea, but I have my doubts as to whether humankind could ever manage it, both ethically and scientifically.
