Subsequently, it was demonstrated that older adults can be recruited to participate in intensive physiologic and clinical evaluations in cohort studies, with 4to 6-hour examinations carried out in both centralized and home locations (5-7), and that long term retention in such studies is high. For example, after 10 years of annual examinations, the rate of cohort retention for adults aged 65 years or more in the multicen-
