So the question is: you don't care about the numbers and fill them automatically, as they all have the same chances to win, or you tend to pick your preferred ones (birthdays, favourite numbers,...) manually?
I think that people always prefer to pick up their "lucky" numbers
(like birthdays for instance) because they believe that those numbers are very significant for them
though all numbers are statistically equivalent. . My profession is related to medicine and there was a case in my practice when the patient flatly refused to be placed into any ward numbered differently with his birthday.
