Episode 289: Use cream that’s cheaper

In episode 289, James and Mike slip into the quagmire of moisturizers and anti-aging creams. We look at what ingredients are in moisturizers and the evidence behind the anti-aging products. At the end they both feel like they’ve aged 5 years and there’s not a cream on the market that will save them.

Show notes

GLYCEROL (glycerin), propylene glycol, butylene glycol, alpha-hydroxy acids (glycolic acid, lactic acid), urea

1% Silicones

DIMETHICONE

2% Herbal extracts – Most added with no clinical evidence they do anything and often the reason for allergic reactions

Episode 288: Media and a machination of the mind – PART II

In episode 288, James and Mike continue discussing their experiences evaluating and interacting with the media. We talk about a few examples of spin – UKPDS spin, Dr Oz/The Doctors spin and so on. At the end we quote Jon Stewart who said “The best defence against bullshit is vigilance. So if you smell something, say something.” We implore you to not complain about the media, but rather become the media by writing and publishing.
