Memory is important for everyone in all ages. How to improve it? It is a complex question. I have several suggestions. Firstly, have enough rest. Enough sleep can make sure brain works normally, because when people sleep, their brain and other organs also can rest. Enough rest can provide enough energy. Secondly, keep always thinking. Do not get used to the current situation. Keeping thinking when meets things can exercise brain. Thirdly, eat some healthy food that is good for memory, such as, radish, cabbage and spinach. I think these are helpful to improve memory。
