There is no safe form of tobacco. At least 28 chemicals in smokeless tobacco have been found to cause cancer (1). The most harmful chemicals in smokeless tobacco are tobacco-specific nitrosamines, which are formed during the growing, curing, fermenting, and aging of tobacco.

For example, if you were born in 1943 or later, your benefit will increase 8 percent for each year that you delay receiving benefits, up until age 70. In addition, working past your full retirement age has another benefit: It allows you to add years of earnings to your Social Security record.
In between 1954 and 1960, the full retirement age 'steps up' by two months for each year. For instance, if you were born in 1955, it's 66 years, 2 months. Age 70: Once you reach age 70, your Social Security benefit no longer increases based on you waiting to collect. As a result, even if you are still working a full time job, have enough income from other sources to cover your costs of living, and expect to live to age 100, you should start collecting from Social Security once you reach 70.
