This isn't unusual, not for a typical Aquarius. Science as well as the science of the mind, psychology, all has a an appeal. Social studies and social work are strong interests, as well. Cooking is not usually a strong skill with Aquarius, though. Aquarians are adept at turning great changes into challenges and hence a fight worth fighting for, but they do have a problem with the small changes day to day.
Big problems are no problem, but little irritants are a major source of discomfort.
It is possible to communicate with an Aquarius without speaking. Or maybe some old-time country like Bob Wills. In my limited observation over the past 20 years, what I've seen more often than not, is that an Aquarius in a grocery store buys hardware. You know, a cooler for the upcoming picnic, maybe some lawn furniture. However, what same Aquarius will go to the department store and find food stuffs to buy.
