The link between "life-quality" and longevity is widely accepted; although the most compelling evidence unfortunately is "negative" in nature, in that it relates to the bad effects of poverty, bad diet, excessive stress, and the like.

The mind-body link however is now becoming more understood in terms of its detailed mechanisms (e.g. hormonal control mechanisms). There is no doubt that apparently subjective concepts like "well-being" and "relaxation" really do have important practical health and longevity consequences.

The logical conclusion would appear to be that it is well worth paying attention to factors like relaxation, if one has any opportunity to do this. (It is worth recalling that virtually every traditional society has its quota of prescribed festival-days.)

And, given the well-proven benefits of fasting (detailed in other sections), it certainly makes sense to get the best value from one's (usually strictly limited) free time by combining a supervised training in this and related techniques with a relaxing holiday in attractive surroundings.
