Problems With The Data Sets

Freezing caused the brain of the man to be slightly swollen, and his inner ear ossicles were lost during preparation of the slices. Nerves are hard to make out since they have almost the same color as fat, but many have nevertheless been identified. Small blood vessels were collapsed by the freezing process. Tendons are difficult to cut cleanly, and they occasionally smear across the slice surfaces.

The male has only one testicle, is missing his appendix, and has tissue deterioration at the site of lethal injection. Also visible are tissue damage to the dorsum of each forearm by formalin injection and damage to the right sartorius from opening the right femoral vein for drainage. The male was also not "cut" while in standard anatomical position, so the cuts through his arms are oblique.

The reproductive organs of the woman are not representative of those of a young woman. The specimen contains several pathologies, including cardiovascular disease and diverticulitis.

Famous quotes containing the words problems with, problems, data and/or sets:

    In many ways, life becomes simpler [for young adults]. . . . We are expected to solve only a finite number of problems within a limited range of possible solutions. . . . It’s a mental vacation compared with figuring out who we are, what we believe, what we’re going to do with our talents, how we’re going to solve the social problems of the globe . . .and what the perfect way to raise our children will be.
    Roger Gould (20th century)

    If we fail to meet our problems here, no one else in the world will do so. If we fail, the heart goes out of progressives throughout the world.
    Eleanor Roosevelt (1884–1962)

    To write it, it took three months; to conceive it three minutes; to collect the data in it—all my life.
    F. Scott Fitzgerald (1896–1940)

    Certain anthropologists hold that man, having discovered tools, ceased to evolve biologically. Animals, never having discovered them, continue to fashion drills out of their beaks, oars out of their hind feet, wings out of their forefeet, suits of armor out of their hides, levers out of their horns, saws out of their teeth. Whether this be true or not, all authorities agree that man is the tool-using animal. It sets him off from the rest of the animal kingdom as drastically as does speech.
    Stuart Chase (1888–1985)
