Gradual aging in your 30s, 60s and 70s: Age researcher lists seven rejuvenating routines. US scientists at Stanford University in California investigated how humans age.
According to their study, biological aging does not occur continuously, but rather abruptly in the fourth, seventh and eighth decades of life. These three periods of life are crucial for the biological aging process because they bring about significant changes in the body, according to the researchers. Scientists suspect that this increases the risk of developing age-related diseases.
