Drink your spinach! The leafy green is an excellent source of iron, folate, and vitamins A and K. Like other leafy greens, spinach also provides fiber, magnesium, and calcium. Iron carries oxygen throughout your body so cells can produce energy. When your body is low in iron, you may feel fatigued and weak.
A housing cooperative, or co-op, is a legal entity, usually a corporation, which owns real estate, consisting of one or more residential buildings; it is one type of housing tenure.
When you acquire a home in a housing co-op, you don't actually buy real estate -- you buy shares in a corporation, whose only asset is the property. This corporation owns the home you live in; you own no greater part of it than any other member.
