Paragraph 1
A new study suggests that the
of children a woman has might affect her
of ageing and her lifespan. Research from the University of Helsinki in Finland found that women who had five children or
, or no children, aged faster than those who had a
number of kids. Researcher Mikaela Hukkanen said: "From an
biology perspective, organisms have limited
, such as time and energy. When a large amount of
is invested in reproduction, it is taken away from bodily maintenance and repair
, which could reduce lifespan." She added that the
of shorter lifespans of women who never gave
was "surprising".
