Keep your memories by recalling them frequently. Every time you remember something, you make a new copy in your brain. Recalling memories is like making a backup. I'm 45 and I still remember things from as early as 3. I remember the feeling of the orange shag carpet in the house I grew up on my toes. I remember going down a waterslide on my uncle's lap and my cousin teaching me how to ride a bike. I remember the feeling of bass in my stomach when the marching band practiced across the street. Keep recalling your memories.
