Well, here’s the thing. If you keep on having sex and your sperm count is good enough, the odds favor you having children unless someone is using a contraceptive. Talk to governments around the world, and they are genuinely worried about the falling birth rate. We are rapidly moving to a world where there are going to be more old people than young people. Sorry, that does need a minor clarification. There are more older people than babies. The governments are worried about who is going to look after all these really old folk. The managers of pension schemes and medical plans foresee there not being enough money coming in from the people still working to pay for all the retirees. Perhaps even more importantly, humans could start dying out unless the birth rate increases.

This is all the fault of these scientist types. They had to go and work out the link between sexual activity and babies. Before anyone made the connection, couples just mated and then wondered where all the kids came from. Because the mating was fun, there were lots of babies and the world’s population grew. Once someone ate the apple, there was birth control and a lot of the fun disappeared as either it was pulling out early or wearing some really uncomfortable "protection" (it both prevented conception and limited the spread of diseases). But these scientists, now properly sorry for their sins, came back with better condoms and contraceptive pills. This put the fun back into sex without having the babies spoil it all nine months later.

Except, that is, for some older men who actually want to leave their genes behind. In November last year, the Brits celebrated Mr Roden. His claim to fame? At the age of 71, he fathered twins. This made him the oldest father of twins and earned him a place in the Guinness Book of Records. For those of you who like all the gory details, this gives him a grand total of twelve children. Not being superstitious, the happy couple are planning to have another. The bad news for us is this man has remained sexually active without having to rely on little blue pills. How does he do it? He eats a diet based on the vegetables he grows in his yard, he does not smoke, drinks only occasionally and has sex regularly. He uses it rather than risk losing it. For the rest of the human race that prefers not to go out and dig the yard, smokes a pack a day and never says no to another drink when you’re buying, there’s the option to buy cheap viagra online without a prescription and go for it with your partner. If the risk of babies bothers you, there are many ways in which you can have the fun without the consequences. Except, of course, when it comes to those unfortunately diseases. No matter how wonderful viagra, it’s not a barrier. If you are going with casual partners and uncertain of their medical history, wearing a condom keeps you safe. Should you reach seventy and decide you want children, you will still be in the race.
