I've been on that site before. If the teachings are valid, I'm an old soul too, probably in the beginning stages. I go right on down the line on how old souls are, and it fits like a glove. None of the other ages fit.
On the other hand, maybe it's all my human personality. Maybe I'm just a grumpy lazy loner old man (at 49)?
One thing that bothers me about the michael teachings is the nonsense on "jesus". Prove jesus existed in the first place. I can either believe what this "michael" says, or I can read someone like
http://jesusneverexisted.com/ He is more believable than this "muchael".
THen there are other reincarnationists that try and prove reincarnation was in the bible and try and show how it's compatible with xtianity. It's not. I was a xtian. It's like they are trying to cater to the same kinds of people that would have burned them at the stake in the not too distant past.
