Watch your step: why the 10,000 daily goal is built on bad science

How much is good for us

The intensity of exercise should also be taken into account. Increasing your heart rate may be more important than the exact number of steps taken.

Added antioxidants

In the 1970s and into the 80s, research was done where mice were given a variety of supplementary antioxidants in their diet or via an injection straight into the bloodstream.

The result showed that an excess of antioxidants didn't stop the onset of disease or extended lifespan.

Antioxidant supplementation
  • In 1994, one trial followed the lives of 29,133 Finish people in their 50s who all smoked. Some were given beta-carotene supplements. The group that supplemented with Beta-carotene had a 16% increase in lung cancer.
  • Another study shows a breast cancer increase of 20% for postmenopausal women who supplemented with folic acid.

The 5-Hour Rule

The most successful, busy people in the world dedicate at least 5 hours a week to deliberate learning.

The 5-Hour Rule is the most critical practice we can all adopt for long-term career suc...

The Simple Math 

It takes about 6,400 hours of class time and studying to get a 4-year degree. Assume that it takes you only 5,000 hours to master your field.

While you are happy that you've prepared for your profession, the knowledge you've learned is fast becoming outdated. We can safely assume that in 10 years, 50% of the facts in the field would be outdated. This means that for you, just to keep up in your current field, you'd need to learn 5 hours per week, 50 weeks a year.

Trends To Consider

When we consider the future of work, there are two trends we should keep a note of. They are:

  1. Half-life of knowledge
  2. Law of increasing learning
