A new research has suggested that strong people are almost twice as likely to be interested in sexual activity compared to those in poor physical condition.

The study has been released on bmj. com.

According to the study's outcomes, at 30, males have a sexually active life expectancy of about 35 years and for females it's almost 31 years.

While at the age of 55, the figure transforms to almost 15 remaining years for males and 10 years in case of females. This gender difference decreases for people with a spouse or intimate partner.

While sexually active life expectancy was longer for males, they lost more years of this activity owing to deprived physical condition than females.

To reach the conclusion, authors Stacy Tessler Lindau and Natalia Gavrilova from the University of Chicago used data from two representative research groups in the US.

One group comprised more than 3000 males and females aged between 25 and 74 and the other included group comprised more than 3000 males and females between 57 and 85 years of age.

The outcomes of the study disclosed that males are more likely to be sexually active, report a good sex life and be interested in sexual activity than females. This dissimilarity was severest among the 75 to 85 year old group, where almost four out of ten men compared to less than two out of ten females were sexually active.

The authors said, "Sexually active life expectancy estimation is a new life expectancy tool than can be used for projecting public health and patient needs in the arena of sexual health and that projecting the population patterns of later life sexual activity is useful for anticipating need for public health resources, expertise and medical services."
