Now I'm the opposite; were I younger and had the money I would love doing something like that. That one has already been done so it would have to be different, but wow what an experience, and not really that dangerous.
You may think Felix had some steel "you know what's" but think about Mr Joseph Kittinger who did the same thing (well nearly....19miles compared to 24miles....) back in 1960.
This was before advanced pressure suits and reliable heaters in the capsule.
If you get a chance to see the video of Jo Kittinger taking his plunge you will understand that this guys "you know what's" must have been bigger than Ben Hur because "nobody" had done this before.
BTW Jo Kittinger held the record until Felix did his jump, also Jo was the director for Felix (seeing he was the only person qualified).
Here is a bit of info regarding Jo Kittinger:
