Probably not one for the squeamish, the show explores this sticky subject in extraordinary detail. Michael performs six experiments with his own blood, including injecting it with snake venom, and even seeing how it tastes by cooking it into a black pudding. Yum!
Most intriguingly of all, he discovers how young blood may in fact hold the secret to science's Holy Grail - reversing the ageing process.
The offline editor was our very own Joe Speirs and with producer/director Nathan Budd, executive producer Jaqueline Smith and series producer Graeme Thomson they all made sure the programme flowed beautifully. The online and grade were taken care of by 422 as well.
The Wonderful World of Blood is on tonight at 9pm on BBC4.
