According to the most recent data from the Social Security Administration, the life expectancy for a 42 year old male is an additional 36.94 years, for a total life expectancy of 78.94 years.
Male life expectancy tends to be lower than female life expectancy. According to Harvard Medical School, it's theorized that this is because men tend to take more risks, have more dangerous jobs, are more likely to die of heart disease, commit suicide more often than women, and are less likely to go to a doctor.
According to the Social Security Administration's same data, a 42 year old male's probability of dying within one year is 0.2828%.
The probability of death is significantly higher during the first year of life and then drops significantly when a child is one or two years of age. Male probability of death tends to be higher than female probability of death for the same age.
