Howdy. Just stopping by to ask any of you lads if something like a true 48 hour sleep schedule is safe and something that can be trained over time.

I've heard a few historical figures like artists used to do it and I often feel like I'm able to stay up for multiple days at a time, but I'm unsure if it's actually safe to do so. Will attempting a 48 hour day turn my brain to mush?
