Search for eternal youth

There have been reports in the Press recently regarding experiments on mice. Apparently if older mice are injected with the blood of young mice, the effects are interesting The older mice are more energetic and  seem mentally to be more alert.
This observation has led some people to believe that the elixir of youth eventually will be discovered. Of course it is hard to tell whether an old mice will change in appearance.
Older people obviously would be the ones who demand this product but the side effects are unknown,
Grandma and Grandpa could find themselves flush with a sudden surge of libido. Imagine if you will Nan and Cramps having a bit of confit dámour in the bedroom ( maybe on the kitchen table between the ketchup and HP sauce) when they would a break and nibble on a piece of hardened cheddar. On the plus side this would not be a problem as their teeth would be growing,  albeit only two; further trouble might have them  composing themselves, breathless and struggling with  entangled tails .
Boggle.

P.S. Unclear why Dracula wears a dinner suit..perhaps some oblique reference to the blood-thirsty upper class in days of yore?
