ages are 1,5 and 7, the children must be of different ages (assume same
mother) the weight of the oldest limits it (I assume the child is rathe thin)
other permutationns of the younger ages are possible, but most age the
friend rapidly, this gives his age as 35, not unreasonable for the friend oa a
person with a 7 year old son.
