Mobile phones: how safe is 'safe'?

Article Abstract:

Cellular phones emit radio-frequency radiation (RFR), a type of electromagnetic radiation. Some researches have observed non-thermal effects of exposure to RFR, such as changes to complex molecules and body cells. Evidence that these effects are directly related to RFR is incomplete, but to be safe, consumers should use a regular phone whenever possible, limit duration of cellular phone use, and hold the phone a little bit away from the head when talking.

Article Abstract:

Credit card reward programs are a means to earn points toward airline trips or other premiums. However, they should only be used if they do not make purchases less convenient or more expensive. Other considerations include point expiration periods, restrictions on rewards and annual credit card fees.
