My dear, those huge profits in aspirin....

"That pretty much says it all. If not, Google "aspirin dangers". And then check and see how many of the aspirins used in studies which showed benefits for reduced risk of stroke and/or heart attack were buffered with magnesium. All of the early studies which showed benefit used aspirin with magnesium and I suspect we may see some of the same effects for the anti-cancer aspirin products."

That's a silly back door approach to an alien conspiracy theory that has no validity whatsoever.  I take an aspirin each day and I haven't seen a buffered product on the shelf in years.  In fact, it's difficult to even find "Bayer" on the shelf any more particularly when Costco competes with them so well. 

Those studies ALL include people in them who are on a healthy diet and lifestyle and preaching your line has never succeeded.  (In fact, Michelle Obama gets trashed every day for promoting that same idea.)  So, at the cost of aspirin these days I figure it costs me a good $3 a year to follow those guidelines and there are many other benefits to it besides cancer prevention - which is not why I take it.  My goodness - Costco's bottom line (oh how I love those bottom lines) is going to really benefit from my $5 purchase every eighteen months.

From the original post:

"Aspirin reduced the risk of a cancer death by 15 per cent compared with control subjects, and this improved to a 37 per cent reduced risk of a cancer death for patients taking the medication five years and longer."

What is it about the 37% reduced risk of cancer deaths is it that you don't like? 

Having spent a career in Information Technology it was commonplace to run into the Not Invented Here syndrome over and over again - at a horrible added cost to my employer. 

NIH = Bruised ego.

Not invented here

Not invented here (NIH) is a term used to describe persistent social, corporate, or institutional culture that avoids using or buying already existing products, research, standards, or knowledge because of their external origins. It is normally used in a pejorative sense, and may be considered an anti-pattern. The reasons for not wanting to use the work of others are varied but can include fear through lack of understanding, an unwillingness to value the work of others, or forming part of a wider "turf war". The opposite culture is sometimes denoted proudly found elsewhere (PFE) or invented here.

As a social phenomenon, "Not Invented Here" syndrome is manifested as an unwillingness to adopt an idea or product because it originates from another culture, a form of nationalism.

In computing

An argument for NIH is to guard against an aggressive action by another company buying up a technology supplier so as to create a captive market. This may also guard against future supply issues due to political unrest or other issues.

In programming, it is also common to refer to the NIH Syndrome as the tendency towards reinventing the wheel (reimplementing something that is already available) based on the belief that in-house developments are inherently better suited, more secure or more controlled than existing implementations.
