The most notorious rock band ever. Including Nikki Sixx (bass), Tommy Lee(drums), Mick Mars(guitar), and Vince Neil(vocals). These guys could do anything.
Kickstart My Heart was about how Nikki Sixx died and came back to life when he was injected with adrenaline. If you look at the lyrics you will notice that they are about adrenaline filled activites for example skydiving naked (fuck thatd hurt)
