Homework Check
Most people are aware of the need to keep their bodies healthy but what about their minds Your brain is an 1 organ / order of the body, just like your heart, so it needs to be exercised! I retired last year and I found that after 2 nearly / merely a few months, I was getting forgetful and often couldn’t 3 locate / violate items such as my keys. I realised that I needed to make some changes to my lifestyle. Now I do 4 crossroads / crosswords in the newspaper and other word 5 puzzles / puddles I find online. It helps keep me alert and my mind feels clear. I also realised that my diet was really poor and full of 6 junk / joint food. Now I’ve increased my 7 uptake / intake of fruit and vegetables. They 8 contain / complain lots of vitamins and mineral that are so good for my brain. Finally, and probably the most difficult for me was joining some new clubs. It’s important at my age to get out of my 9 comfort / conflate zone. Making new friends and learning new skills keep the brain active. I joined a chess club in my local area and I enjoy it so much.
