The body of Jesus Christ "grew and waxed strong" and "increased in. . .stature." Luke 2:40,52
Jesus couldn't have been frail physically to labor as a carpenter.
He was strong in body without sickness.
It's believed that Jesus' natural body which aged and would have been subject to physical death at about 120 years if He hadn't been crucified.
It was His glorified, resurrected body which ascended and now lives at the right hand of the Father.
