english: Almost all projects of this kind fall apart within a decade because too many people drop out of the study, or funding for the research dries up, or the researchers get distracted, or they die, and nobody moves the ball further down the field.
non_english: Skoro svi slični projekti se raspadnu u roku od jedne decenije jer prevelik broj ljudi napusti istraživanje ili finansiranje istraživanja prestane ili istraživačima nešto drugo odvuče pažnju ili umru i niko ne nastavi započeti posao.
