Hello @dull-deku , may be I can help to answer you, I studied and listened some where that doing fingers pressing exercise for 20 minutes daily along with yoga and brain focusing helps a lot in improving your memory. As the fingers exercise will stimulate the receptors and doing this on regular basis will create a fast connection between the brain and receptors. Because when brain will pick the same thing continuously , it will start focusing in short time,
I hope I have delivered it to you
More over, I have also written this tip into my contest post on This topic, you can visit that for better understanding.
Thank you 😊
