I have used this organizer for the last 3 years for both of my daughters. Each book is set up for one year's worth of pages. It serves as a fun visual guide for students and excellent goal maker for parents. Believe it or not, my daughters will do anything to earn those check marks and little stickers as a reward. You can get as creative as you want with the check boxes and stickers. Page is divided by categories (warm up, scales, techniques, repertoire, orchestra/quartet pieces) and this helps students/parents organize the practice for each day. Since whole week's worth is on one page, this helps us set a goal for each day and for each week as well. Check boxes serves as a visual incentive for students to see how much progress they are making and how hard they worked to get there. My girls and I enjoy using this organizer year after year and will probably continue to use them for many more years to come.

In a healthy, vitamin D–replete, elderly population (70–90 y of age), no correlation was found between serum 1,25(OH)D 3 concentration and knee-extension strength, although both declined with age ( 61 ). This finding was the same in the study by Grady et al ( 62 ), in which 98 healthy, mostly vitamin D–replete, volunteers (>69 y of age) showed no significant differences in knee extension or flexion strength after treatment with μg 1,25(OH)D 3 /d or a placebo for 6 mo. Although muscle strength declined by %/y in this population, serum 1,25(OH)D 3 concentrations remained stable with age, increasing only moderately after 6 mo of treatment.
