Which statement is generally true about retirement?
nexus9112 [7]

Retirement is the leaving of one's of occupation. This means you cease to be involved in active service in a job or occupation especially when one is considered old and of retirement age.

During retirement, retirement benefits and pension are usually made available to retirees. However, one's income will come to a decline which makes most people scared of retirement. Keeping up with the standard of living they are used to becomes difficult as income to sustain such may not be available.

Therefore, the general statement that is true about retirement is <em>B. your </em><em>income </em><em>will decrease, while your </em><em>expenses </em><em>will increase.</em>
