David Blaine has been upside down since yesterday, and today his medical team will be on hand at Wollman Rink to check in on their patient. There have been some concerns about what being in his position for 60 hours can do to the human body (like blindness!), so stay tuned for what's likely to be a dramatic yet reassuring press conference with the docs.
