In some cases stress functions as a catalyst that, in fact, leads to death by directly compounding existing health complications, such as heart disease. Whether it is work-related or a death in the family, stress can be the result of a variety of events in one s life.
The Vitamix S30 is the newest addition to the Vitamix lineup and their first entry in the personal blender category. This new blender is much smaller in terms of size and horsepower, but is priced very closely to its full-sized counterparts.
As far as I know, Vitamix has not changed the preset programs over time, but, for completeness, the tested Pro 750 and Pro 500 were purchased in 2013, and the S55 in 2015. If you have one of these models and its programs that do not match what I measured, please let me know and we can investigate.
