It can be both interesting and life-saving to look at the DNA analysis of health conditions. For example someone knowing they have the BRCA gene might encourage them to seek cancer screening opportunities sooner. Particularly if they are adopted and don’t know their family health history.

Thankfully no nasty surprises surfaced, but I was intrigued to find out that I have some sort of elite athlete gene. You wouldn’t know it as my best friend and I like nothing better than to chit-chat at the far corner of the sports field and watch the lacrosse ball go spinning by. Must be one of those recessive genes…
