False memories proven in most kids, implanted by adults, sometimes by accident, but it is possible to have genuine old memories, even at age 2. **NO IT IS NOT rare!!!** ============ Normally, you have to keep refreshing a memory event at age two, every year or so, to keep it alive until the day you die. However, some people who move away from a home at age 2.5 when age 40 or 50 can be driven to that address and they recall all sorts of things about the time they lived there at AGE 2 !!!!!! Most people have either implanted false memories, or imagined, but you can cellular-refresh a genuine memory from age 4 onward of your memories when 2. I actually have a memory BEFORE AGE 2, complete with 5 faces, the room, the paintings, and a few spoken sentences in the room, and I realized what room it was when i revisited at age 4 , then refreshed THAT memory all my life every year or so. So I have a vivid accurate PRE AGE 2 memory with neurons refreshed and reconnected fro many years.
