Are you curious about your genes?  Perhaps you would like to know what your genetic ancestry is or if you carry any disease related genes.  I am not aware of any companies that provide whole genome sequencing direct to the customer, but several companies sequence part of the genome. Direct to the customer means that you can order the test directly from the company, instead of a doctor ordering it for you.  I have used 23andme.  It cost $99, and all I needed to do was to spit into a tube and mail it back to the lab.   Here is the link:  https://www.23andme.com/

For $99, you can find out about your ancestry and even the percentage of Neanderthal DNA you might have.  It takes at least 3 weeks to get your results.  23andme can no longer provide medical information related to your DNA, but it does provide your raw data, which you can download and then run through a number of databases, that can help you make sense of it all.  I have used several of these databases.  http://www.snpedia.com/index.php/Promethease  is a good one to start with.  It costs $5 to generate a report.
