I was reading about various memory techniques : mnemonics, memory space, peg system, space repetition etc . They are used when I have to memorize something by myself for longer duration.
There are many other memories which are in my mind but I dint memorize them by myself. They are automatically stored. Like : my travel experience, some childhood activity etc . Some of them are faded some are still very clear. I can visualize them clearly.
But there are some memories, I cant visualize them. But I still remember. For example : if I try to visualize or write position of 'G' key on laptop keyboard, I can't. But still when I type, my fingers know its exact position. Similarly, if someone asks me to write my national anthem, I can't. But I can sing it without any mistake. Why does it happen so. Can't I remember everything in this way instead of any other memory technique? The advantage of this is quick recall.
