Although familial Alzheimer's disease is responsible for a small minority of cases of Alzheimer's disease, it is important, not only for the families with it, but also for what we can learn about all of Alzheimer's disease from it.
Simple syrup. A basic sugar-and-water syrup used by bartenders as a sweetener to make cocktails. Simple syrup is made by stirring granulated sugar into hot water in a saucepan until the sugar is dissolved and then cooling the solution. Generally, the ratio of sugar to water can range anywhere from 1:1 to 2:1 by weight, and similarly by volume due to air in the granulated sugar.
Simple syrup is a common ingredient in drink recipes, whether you're making cocktails or iced coffee. Don't be tempted by bottled sweeteners; if you can boil water, you can make simple syrup. It's an easy step but an important one. By dissolving granulated sugar in hot water before adding it to cold beverages, you ensure an even distribution of sweetness without any gritty crystals left in the bottom of the glass.
