I disagree, I sequenced with nebula genomics years ago.. you can understand risk factors for various problems so that you can start interventions that make sense way in advance.

Did you actually find any actionable results? When I had my genome sequenced professionally they told me I literally had no SNPs in my genome that were associated with deleterious mutations. And even if you do, there are only some treatments- and those treatments usually have clinically validated tests that are accurate.
