I've never found any scientific fact or item or whatever as empowering or life affirming as a good shag, or running along a cliff top, or jumping into a cold river, or laughing your head off with your mates down the pub, or hurtling downhill on your mountain bike.

We all need a little comfort sometimes. If you transcend such needs you've turned into a droid, you probably have white juice between the looms of wires in your artificial limbs, and you'll never dream, and you'll probably go rusty eventually, or be superceded by a newer model and get thrown away. That's science for you....
