I agree with most of points 13, 14 and 15.
13. We can make our senior citizens more productive and alive but we must recognize their need (at advanced age) too. Facilities and access for their transport, health and safety must be provided 'at school'.
14. I would put the teaching of skills to be able to look after themselves in various aspect of living and being a member of a community/society at the top of the list. The skills are language (speaking and listening -- or communication); interaction (observing, understanding and 'playing' rites, traditions and rights, and environment); hygiene and health -- physically and mentally (strong body-strong mind); social responsibilities ('right and wrong').
15. Yes and (in its place) promote (volunteer) 'buddy' or 'mentor' activities with venues (like community halls, botanical parks, roadside gardens, bicycle tracks, swimming pools, sports fields, ...) (with the money saved from extra classes).
Schools can be used as venues when in out-of-class-time for this purpose too in combination with point 13. Volunteers for many out-of-curriculum activities (arts, crafts, dancing, singing, acting, trades, horticulture, sports, religious seminars, ....) can be draw from the community or supporters' organizations.
