Brian Johnson is an interesting case. If you've got the money, certainly the thought "can I live longer?" crosses your mind, but no one has so far committed to the lifestyle "required" to live longer. Ignoring whether anything Johnson does is actually working, he's obsessive over his self image and his ability to claim his "blood work looks like an 18 year old's"<p>It's also interesting how he's clearly had facial plastic surgery, but is less keen to mention that amongst all the vitamin infusions and blood transfusions he's undergoing on a daily basis.
