Don't forget the other ways to lower cardiovascular risk. The polymeal is supposed to prevent up to 75 % of all cardiovascular disease. So, if you don't succeed one way, try the other.

Also, check riskfactors like endangering hierarchical situations or 'type D'. The "D" in type D stands for "distressed" and was found to increase adverse outcomes in cardiovascular disease. Type D is a stable, broad personality trait marked by the combination of a high degree of negative affect coupled with inhibited self-expression in social interactions. The type D individual is reserved and insecure -even timid- anxious.
It's rather odd that we do have our cars checked every 20.000 miles or so; that we do clean our computer harddisks, but that we don't regularly have our selves checked, cleaned and exercised in psychotherapy training or workshops, to reduce the risk factors, that most of us carry. One way or the other.
