I might want to be halted at age 22 and following is my rationale :
Suppositions:
When we say maturing process is halted, it implies that I get the chance to have all the physical properties that a run of the mill solid 22 years of age has.
My psychological capacities additionally stay at 22 years old which implies I can process musings and thoughts at same rate, my memory stays practical as at 22 years old and so forth.
My insight and experience is amassed. It isn't so much that I wake up ordinary and overlook everything that happened yesterday henceforth not growing up as a man. Since you learning and experience makes you what you are, not your age and physical capacities. So I would prefer not to be screwed over thanks to the knowledge and basic leadership abilities of a 22 years of age. A run of the mill vampire would be a decent case of what I am going for barring the parasitic and night creeping obviously.
