Maybe platelets is nothing to worry about, Mike 🙂

I just came across an interesting platelets study:

Lower platelet count in healthy centenarians correlates with dispersion of the QT interval

Results: Centenarians showed a lower platelet count compared with controls, which was significant with respect to older controls, group B (p<0.05). QTd values did not significantly differ between centenarians and controls. A significant correlation between QTd and platelet count was evident in centenarians but not in controls. This correlation became evident in control subjects with a platelet count < or = 240,000/mm3.

Conclusions: We hypothesize that a reduced number of platelets and the maintenance of normal QTd may contribute to extreme longevity and protect centenarians from cardiovascular events.

Thanks Ron, but that platelets < 200 is associated with an increased all-cause mortality risk would reduce the odds of getting to centenarian status...

In further support of that, in Figure 1, average platelet count in centenarians was ~200
