Aren't the marriage and divorce rates declines simply a function of an aging population?

Pascal and Metal Means
I've found a relation between Pascal triangle analogues and the so-called 'metal means'. What this portends for our understanding of the periodic relation remains to be explored. At least my muse hasn't left me entirely. Sometime I worry, esp. in dry periods. The monsoons are returning at last.
See: http://en.wikipedia.org/wiki/Silver_ratio and the discussion page whose link you can click at the top of the main page- my addition appears at the very bottom of the discussion page.

Cyclo‐oxygenase 2 inhibitors and the risk of anastomotic leakage after fast‐track colonic surgery - Your View
I read this article with interest. Would like to raise the following points for discussion.
Matrix metalloproteinases (MMPs) are members of the family of zinc (Zn) - and calcium-dependent endopeptidases. The MMP family consists of 25 enzymes, which are classified into eight distinct groups according to their structures. Five of them are secreted types and three of them are membrane-type MMPs.  MMPs are produced by various cell types in response to inflammation or tumour progression. MMP-2 is constitutively produced by numerous cell types, whereas MMP-9 is produced by inflammatory cells such as macrophages, neutrophils and epithelial cells of the respiratory tract. MMPs that are produced by inflammatory cells appear to be responsible for microvascular permeability leading to edema and cell transmigration.  This means that inflammation is an integral part of the healing process  By the intake of non-steroidal anti-inflammatory agent postoperatively, the acute inflammatory response and onset of fibroblast proliferation would likely to be delayed and the anastomotic tensile strength would accordingly be reduced  and the anastomotic leakage would then be the outcome.
