There is a genetic trait called Factor V Leiden which will make you predisposed to blood clots (some tests can reveal if you have it). I am not sure if I have it but it can be a factor outside of diet and exercise. But you don't need my case as a warning - studies have linked sitting to death for at least several years now. How valid they are is up for question, but better safe than sorry. :)
While I agree that as a culture we need to prioritize our health a lot more, it's a dangerous attitude to claim that "it's better to be safe than sorry". Doing things out of fear and ignorance is not better than making well-educated decisions. In all fairness, there is plenty of evidence to support that apes (that's us) are not meant to sit all day.
Definitely agree. On an added note (about safe vs sorry) - while in this case I was "lucky" to have my hypochondria be correct, the vast majority of the time symptoms that I worry about are nothing. If I went to the doctor for every little symptom I got, that would be expensive and time-consuming.
