After abandoning my Fitbit device in January because using it didn’t see improvement in my weight (see previous post), I was wondering if I could still measure my risk to develop cardiovascular diseases and other preventable chronic diseases (diabetes e.g.). So, still sitting at my desk (something I do for more than 8 hours a day in theory – probably more in practice), I looked into the ways to monitor my risk for these diseases …

I’ve been using several Fitbit devices since a few years and I decided to stop using them in 2017. My feeling (like many people experienced before) is that wearable devices don’t work. Yes, you’ve read correctly: I was a big supporter of wearables, following the adage “what you can’t measure you can’t manage”, but not anymore.
Why do I write that? What works then? And what does that have to do with the title? Continue reading “Do you gain weight before moving to the USA?”
I wish you all a very happy new year 2017. This time of the year is when you usually do new resolutions. And, among others, I resolved to post more often new ideas and thoughts on at least one broad topics: quantified self.
As I moved to a new office, I met new colleagues and one of them brought her own coffee machine and placed it on her desk. It’s a bright red Nespresso machine, a kind of statement that the owner doesn’t drink the free coffee offered in kitchenettes on all floors:
Given that the company has a professional Nespresso machine downstairs (i.e. similar quality of coffee but with capsules of different shapes), I was wondering if this is really worth buying. The calculation is simple …
On one hand, the “public” Nespresso machine sells 1 capsule at 0.50€ and pours the water (through the capsule) in a cardboard cup.
On the other hand, the cheapest personal Nespresso machine you can buy in Belgium costs 199.00€. The cheapest personal Nespresso capsule you can buy costs 0.35€ (let’s forget for a moment you have to buy them in multiple of 10 and there are savings to be made if you buy large quantities).
Therefore the upfront cost of the personal Nespresso machine tells me it’s more expensive to have my own machine on my desk. But after how many capsules (i.e. cups of coffee) does it become cheaper to have my machine? The equation is easy: 199.00 + 0.35 * x = 0.5 * x (where x is the number of cups of coffee). Solving it tells me I need to consume 1,327 capsules from my machine in order to get my coffee cheaper than on the “public” machine. That is more than 3.6 years if I drink 1 coffee per day – only slightly less than a year if I drink 4 coffees per day (which is a lot).
Of course, this simple calculation doesn’t take into account electricity, water, cleaning cups or the cups themselves ; they are considered free in both situations (which they are, in practice). It doesn’t take into account neither the convenience of not having to stand up, go down a few stairs to the “public” machine. But, for the future, it doesn’t take into account neither the benefit of having moved more during office hours (more than just sitting the whole day).
So, given some assumptions, having my own Nespresso machine on my desk is probably not economically viable at a reasonable time horizon, unless I drink a lot of coffee and if I value the convenience of not losing a few minutes to go down to the “public” machine. But going downstairs for a coffee prevent me from sitting for too long at my desk and it allows me to meet other colleagues downstairs. I’ll keep this habit! 😉
The terminator may not come at any time soon but medicines should be coming soon at a printer near you …
Mid last year, Gartner mentioned “medical applications [of 3D printing] will have the biggest impact in the next two to five years“. With 3D printing you can already create a lot of physical artifacts and medical applications go from building medical equipments to prosthetic parts, but also blood vessels, bone, heart valve, cartilage, etc. Complete organs are not too far, with companies like Organovo already printing functional liver assays, prospects to restore a body by replacing or consolidating personalized parts seem interesting.
On the other side, restoring a body function by providing personalized molecules was a dream so far. Preventing body malfunction via similar systems is too.
I recently watched and read about Lee Cronin’s laboratory work and these dreams may come true, one of these days. In a TEDxGateway video in 2013, Prof. Cronin explained briefly how he did it. Last December, they published their method with a basic application in Nature Communications. What I also liked is that, beyond the technical capabilities, this research is based on common components (right) and free software that are available for everyone. And Cronin also insisted on compatibility between “recipes” and the possibilities to exchange them as well as source code – one day, will their software be released on Github like some of their 3D models as STL files?
Cronin also talks about pharmaceutical companies releasing blueprints for drugs that could save plenty of lives in emerging economies, for instance. In my opinion, this is however where the technology goes much faster than the ideological framework we live in: pharma companies will not likely suddenly release recipes for drugs that bring them money (no for-profit company in any other sector would, by the way) and the regulatory framework for healthcare is far from ready to accommodate these advances.
Prevention could also benefit from these advances. Synthetic vaccines are in production since two decades at least. If safety is the first argument often put forward in their favor, rapid prototyping and versatile production could one day become possible. It seems it was already tested for flu vaccines. Now imagine to move the “engineering” part in a computer, sending the recipe for the best-adapted vaccine directly to “vaccine printers” in regions where health hazards are likely to occur or as early as they occur … We would also face many corporate and regulatory hurdles. But it wouldn’t be the first field where technology would push broader changes …
With more than 2,400€ collected, our team – Bordet’s angels – can be proud, for a first participation! We are 12th of more than 100 Belgian teams. One key learning is that the gold, old paper display still works better than anything else to raise money.
And it was fun for me, a bit itchy in the end. But with the right trimming tools, this goes away very quickly. Thanks for all my supporters 😉 – your support is worth a thousand thank-you!
And a bonus video that was fun to create …
