Unless you are buying a machine, making sure its offline and doing it all by yourself, DONT sequence your DNA! You're not just condemning your genetic data to whoever might pay to obtain it but that of all your future progeny and even that of all your blood relatives. Its insane how bad the worst case scenario is.
And it also doesn't help you with anything. It has near zero predictive power about your health unless combined with epigenetic data, which you can't get.
It might even make you sicker through anxiety or other nocebo.
It's only really useful as a confirmation for a doctor's diagnosis, and those are done with slightly better data controls.
