Finding out random genetic variations you might be predisposed to. It gives out likely or unlikely expressions you might have. I got the health, fitness and nutritional pack and I saw confirmations of experiences that I've uncovered about myself, like having unordinary grip strength. It's neat to have this kind of validation and proof! I plan to reference my xcode pdfs since there's a lot to digest! I find the vitamins my body would likely prefer to be my favorite part of it. I want something more definitive to understand myself, like not what's "likely", but genes are complicated and xcode just provides what's likely and that's ok. What I would prefer is probably a whole other complex science. It was worth it.
