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. The level of tobacco-specific nitrosamines varies by product.
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.
If you can't or don't want to wait until full Social Security retirement age, it's possible to begin collecting Social Security as early as age 62. While this may seem tempting, you should try to avoid it if possible. Your monthly benefit will be reduced by about 0.5% for every month you start collecting before full retirement age.
