Reading is a must

I think it's a must to read on a variety of topics as much as you can, in order to have a general knowledgebase about your surroundings and events, as well as to keep your brain cells sharp and active. The more you stimulate your brain cells by reading, the better you will be able to maintain your memory capacity as you grow older. So do try to inculcate the habit of reading - it could be others' blogs, magazines and newspapers, books, or whatever suits your fancy.
