Brits too lazy to bonk?

The results of a recent study carried out for Nuffield Health are somewhat disheartening regarding our national libido. It states that 73% of people said they regularly have too little energy at the end of the day for passion with their partner, and 58% of those blamed their barren sex lives on a lack of fitness. Are we becoming a nation of sexlesss couch potatoes?

What do you think?
