Tips for Staying Sharp
It's not abnormal to feel out of it from time to time or perhaps you're feeling a bit sluggish(遲鈍的)when it comes to remembering things. If you're worried about your forgetfulness, try out these five tips to stay sharp.

You've probably heard the term “you are what you eat.” If you decide to eat sugary foods that are heavy with fats then expect to feel lazy and have no energy. But if you decide to eat fruits, vegetables and make other healthy eating decisions you'll find that you're full of energy.
Never stop learning
Challenge yourself constantly---whether it is puzzles, reading, cooking or other tasks that will keep your mind working. If your mind is always learning new things and active, you'll realize that it's much easier for you to learn new things and to function.

However, if you put forth the effort into being health then your body will expel(釋放)the energy you need to achieve your goals.
Ensure enough sleep
