Question 1131024
.


Let me tell you even more:


<pre>
     (Almost) every parent (under reasonable assumptions) once is exactly twice as old as his or her child.
</pre>


Indeed, &nbsp;if the parent brought a child when the parent was &nbsp;X&nbsp; years old,

then after &nbsp;X&nbsp; years the parent will be &nbsp;2X&nbsp; years old, &nbsp;while the child &nbsp;(the son or the daughter) &nbsp;will be &nbsp;X&nbsp; years old 

with the ratio of ages exactly &nbsp;2.



The natural condition of feasibility is that they both are live at their corresponding ages.
