Amazing. I haven't really kept abreast of what's been happening in the world of reproductive science, but I found the linked article fascinating and problematic.
One problem is how we keep track of a person's age. Let's say that life does begin at conception, though conception is a very slippery thing to define, and we are able to put life in a state of indefinite developmental abeyance, then is a twenty+ year gap in a person's life a reason to change our chronological way of looking at age. Probably not for most everyday and medical purposes, but it does seem to add a new wrinkle to the conception>pregnancy>birth>hello world>goodbye world cycle. Maybe in the future we will need to ask a person when they were conceived in addition to when they were born. I wouldn't want to ask when they were thawed out, though.
