Yes. When objects are in orbit around each other, there is a strong pull of gravity between them. For example, we commonly say that the Moon is in orbit around the Earth. However, the Moon pulls back on the Earth as well. This changes the Earth a little. One way we see this happening is the ocean tides.
An annuity is a long term investment that is issued by an insurance company designed to help protect you from the risk of outliving your income. Through annuitization, your purchase payments (what you contribute) are converted into periodic payments that can last for life.
With an immediate annuity (also called an income annuity), fixed payments begin as soon as the investment is made. If you invest in a deferred annuity, the principal you invest grows for a specific period of time until you begin taking withdrawals â typically during retirement.
