    Technically everything moves at c (the speed of light) through spacetime, all the time. Most objects that have mass spend the majority of their motion in the time part, and thus move relatively slowly in space. If an object moves fast in space (where fast is a significant fraction of c) then it moves noticeably slower in time because the total spacetime vector value is always c.

    Photons, being massless, do not move through time at all, and move through space at c.


  • Barkley’s study found that the biggest predictors of shorter life expectancy in adults with ADHD were factors including lower incomes, fewer years of education, a greater likelihood of smoking, shorter sleep duration, less exercise, poorer nutrition and risky driving. He notes that most of these factors are linked to impulsivity — which can be treated.

    “These factors – virtually all of them can be changed,” Barkley says. “Change the factor [and] you change the life expectancy. So none of this is cast in stone.”

    It’s not the ADHD, it’s the impact of the ADHD on how you live,” says Wiznitzer, who is also co-chair of the professional advisory board for CHADD, a nonprofit education and advocacy group for people with ADHD. “Because you’re impulsive, you don’t make the best choices.”

    So basically… diet, exercise and regular sleep… the bad news is, it’s advice you’ve heard all your life and you probably aren’t following… the good news is that the science on this is pretty definite, and a lot of it is stuff you can do for free (well, no financial cost - it will cost you time though).
