A mans deep voice more attractive than good looks According to experts from the U.

While the Hadza are monogamous, extra-marital sex is certainly common. The extensive research group interviewed 52 females and 49 males from the tribe, aged 18 to 55. The interviews took place in Swahili and the voices of the women and men were recorded. When the recordings were studied it was discovered that the deep voiced males had fathered more kids than the non-deep voiced men; the man with the deepest voice acquired ten surviving children, while the one with the best pitched voice had only three. Apicella suggests that the men with the low pitched voices experienced higher testosterone levels possibly, which attracted them even more to females or produced them more attractive to them.The findings on brain magnetic resonance imaging and magnetic resonance angiography remained steady at 1 and 24 months after transplantation in patients with abnormalities on brain imaging. Individuals with elevated tricuspid regurgitant jet velocity or a brief history of the severe chest syndrome had no episodes of dyspnea or documented declines in oxygenation during conditioning. The mean tricuspid regurgitant aircraft velocity before transplantation did not differ significantly from the mean values 1, 12, and 24 months after the transplantation . Although a 6-minute walk test was not performed routinely before transplantation, values after transplantation compared with those in historical settings at our institution favorably.
