short answer NO, or at least a heck of a lot less often
For someone born with ADHD and never knowing any other way of being, it is normal to assume that this is how everyone else is too. Studies, however; show that symptoms occur MUCH more often in people with ADHD. The book Taking Charge Of Adult ADHD - by Barkley has an appendix in which they spell out how common symptoms are in the normal (or as prefer to call it ORDINARY population) vs. those with ADHD and the percentages are dramatically different, as is the frequency of symptoms.
It's about the frequency of symptoms and the impact they have on quality of life.
