Im in the thirties but i can say that im not still that old to lose sight of what i do. SImply at times, I just failed to remember what im to do specially if its important or where i put my things. I tried doing a "list to do" but even that I also failed to update. I know I’m busy at times but it’s not a reason as to why I should forget things…What is the most effective way to enhance memory and maintain being sharp. Please advise….
