Using reversed spelling is not much help. A simple English word is easy to test. Many computer systems have an online spelling dictionary, and it is not much work for villains to write a simple program that tries every word in the dictionary against every login password. Your job title or department name is a bad password. These are easily penetrated.
Any word associated with a personal characteristic is easy for the cracker to guess.
For example, if you are known as a dog-lover, passwords such as spaniel or mutt are less secure. Your auto license, telephone, and social security number are not good bets either. Passwords decrease in security with age. It is therefore a good idea to change your password occasionally. Perhaps every three to six months, or at each quarter-break is probably often enough, although you must change it if you have any hint that someone who should not know it has found out your password.
