"Fifty years have passed... but I do not age. Time has lost its effect on me."

― Jack (Samurai Jack)

"Not bad for a seven hundred years old."

― Sabra/Ruth Bat-Seraph on Gabriel Shepherd (Marvel Comics)

"So you're having a midlife crisis."

"Well...I'm extremely old. I think I'm entitled."

― Dean Winchester and Castiel (Supernatural S10E9: The Things We Left Behind)

"Ah, Sanderson. The decades have treated you well. All grim and grown, are we? No longer Wesley Dodds' Golden Boy, I see."

― Johnny Sorrow to Sanderson Hawkins (DC Comics)

• The user may be suffered from grief as they may watch other people meet the end of their lives which can cause severe psychological effects on the user.

Trivia
