This is a truly controversial and complex issue. Does a person need immortality? Would it not mean a complete lack of meaning in existence. The new day will not be perceived as something amazing and beautiful. There is a good phrase "be Afraid of your desires, they can come true." And the desire to be immortal, in my opinion, is the desire that is better not to come true. The consequences really seem to me more negative than positive. Although, as far as I know, many people now sign a contract to freeze their bodies, hoping that over time humanity will find a way to revive their bodies and return to eternal life.
