Banking your sperm... in blackpropaganda

Every morning, when we wake up, we turn on the radio to pick up Radio 4 - it might be 4.30 am - time for a pee - and then hopefully the drone of the World Service send you back to sleep.
The Today programme comes on at 6 am on weekdays - and there may be stuff on there which keeps you awake - but normally that can send you off too.
Eventually you wake up sufficiently to have another pee - and then listen until you get up.
So this morning there was the news that an expert - as always - had said that with men getting older before they produce children, and the danger of abnormalities being present in the sperm of older men leading to autism in the child etc , young men of 18 should collect their sperm and have it frozen for later use if they were going to reproduce later.
A later discussion thought this was all hooey - not the fact that older mens’ sperm is not so good - but that you should start collecting early.
I thought that too - 18 year old fellow are quite keen on producing sperm either through masturbation or other sexual activity - but their last concern is to worry about the future - one of their main concerns in having sex should be to stop any reproduction.
Charlie Chaplin was producing children with Oona O’Neill well into his seventies - and was doing it the usual way - think Michael Douglas too. Of course, the man’s moment of pleasure is not the end of the story for the woman!
It’s a pleasure for me to have the capability to produce some sperm anyway!
