Vegetarians are divided into three categories; Vegans, or pure vegetarians who abstain from all foods of animal origin; lacto-vegetarians who include milk and dairy products in their diets; and lacto-ovo-vegetarians who consume egg products as well as milk and dairy products. Vitamin B_12 deficiency has been reported in strict vegans. A nutritional analysis was conducted on the dietary intake of a group of 19 vegans aged 7 to 72 years who had been living on a vegan diet for from 7 to 50 years, and on that of age-matched control group. In addition, their serum vitamin B_12 levels were determined. In vegans' diets, 2-4g of nori (dried laver), which contained B_12, were consumed daily. Not a single case of symptoms due to B_12 deficiency was found. There were no stastistically significant differences between the two groups with respect to vitamin B_12 levels. Therefore, consumption of nori may keep vegans from suffering B_12 deficiency.

Little attention has been given to the sexuality of disabled persons, although it is a crucial part of their personal self-identity. The issue of masturbation, in particular, has completely been ignored by the study of disability. Whether or not should disabled men be helped to masturbate? If they should be helped, who should help them, and how? In order to explore these questions, the present study made long unstructured interviews with two carers who have experience in helping disabled men to masturbate, that is, "masturbation aid". The study concludes that these two carers distinguish the "masturbation aid" clearly from other bodily aid or care for disabled men.
