METHOD FOR EVALUATING AGING, AND DEVICE FOR EVALUATING AGING
A method for evaluating aging of the present invention, evaluates a progress degree of aging, based on a fluorescent material which increases in a body, along with the aging of a living being. Moreover, a device for evaluating aging of the present invention, includes an aging determining unit that outputs a determination result indicating the progress degree of the aging, by irradiating the living being with excitation light having a wavelength of a predetermined range, and by performing a predetermined calculation using a fluorescence intensity of a fluorescence spectrum emitted from a fluorescent material which is characteristic in an old stage in comparison with an immature stage, and a controlling unit for a display device to display the determination result which is output by the aging determining unit. According to the present invention, it is possible to simply evaluate the aging on the spot without using a genetic analysis or the like.
