Certainly the 80&amp;#x2F;20 rule probably applies: your suggestions will fix a great many issues for many people, and it&amp;#x27;s definitely worth reminding most people to make several of the changes you suggest -- particularly exercise and sleep.&lt;p&gt;But if the recipe was really that simple for all people, more of us would experience more success.&lt;p&gt;Humans are complex. Not mechanistically complex, stochastically. We&amp;#x27;re chaotic. One set of inputs may produce different outputs, and reverse-engineering the reasons for those differences may be &amp;quot;hard&amp;quot; or impossible. Apps and tracking devices can help reveal small areas where a fractional improvement in control or quality can have very large beneficial effects.&lt;p&gt;Lifestyles and other highly personal factors mean that the application of a simple single formula will be met with varying success. And anyway, you have to measure the outcomes to understand how successful the intervention has been.&lt;p&gt;I&amp;#x27;d also point out that just because you &lt;i&gt;feel&lt;/i&gt; well, it doesn&amp;#x27;t mean that your lifestyle or body (or mind) are healthy. Some attempt at objective data is useful to determine if you&amp;#x27;re really as healthy as you think you are. Sure, you may feel great if you get regular sleep every night. But did you know your sleep apnea puts you at increased risk of cardiovascular disease?&lt;p&gt;Edit: probably a better example... You may feel perfectly fine sitting down for several hours per day. But you&amp;#x27;re at increased risk of a whole range of diseases. A timer set to beep evey 20 minutes to remind you to get up and move may actually add years to your life.&lt;p&gt;This isn&amp;#x27;t a defence of lifestyle or health&amp;#x2F;fitness apps and so on, just a recognition that they work for some people, and for some circumstances. Or so it appears. This is the start of a vast, poorly coordinated longitudinal experiment. We&amp;#x27;ll be poring over the data for years yet.</text><parent_chain><item><author>njharman</author><text>The body works amazingly well when taken care of and listened too. Really. Instead of hyper tracking every aspect of your life [and making assumptions based on that data]  Just exercise, eat well, no caffeine, minimal sugar&amp;#x2F;food after dark, get 10+min of sun around noon, go to sleep when tired.  All of which is almost impossible for 90% of people who are forced into regimented, high stress, excessive work lives.</text></item></parent_chain></comment><story><title>Sense – Wake up when it&apos;s right for you</title><url>http://hello.is</url></story>

I know &lt;i&gt;so many&lt;/i&gt; otherwise smart folks who buy a FitBit and track their caloric intake only to then drive (not go outside and walk) 2 blocks to get lunch at McDonalds or someplace similar. You don&amp;#x27;t need a product&amp;#x2F;app to live a healthy lifestyle... most likely if you are trying to solve a health&amp;#x2F;lifestyle problem by purchasing something, that is just symptomatic of yet another unhealthy aspect of your lifestyle.</text><parent_chain><item><author>njharman</author><text>The body works amazingly well when taken care of and listened too.
