I think you should consider the boiling frog syndrome.
Not aging is as slow as aging, and by the time you realise and accept there is something special with you, everyone else around has already figured it out. Disappearing at that point might be a pretty conspicuous move "that guy [or woman, I wonder why all immortals must always be men... :)] who is 70 but actually looked thirty went missing".
