I very strongly disagree. Firstly because survival is one of the most primal instincts found in all living things, next to reproduction. I see no reason why any person living in a healthy young human body would decide to die, unless clinically depressed (which wouldn't be the case in a healthy body). Secondly, boredom is for the unimaginative. We know almost nothing of our universe. We have explored only a very tiny fraction of our universe. We still have so much to learn. If we lived millennia, we could actually become a space-faring species.
Moreover, I read books, watch movies and tv shows almost every single day and in 26 years of life I have no been able to get boredom. Every year I discover something amazing, a TV show, a book, that encompasses an entire philosophy and a bit of meditation to understand. Especially the older stuff that wasn't so commercially focused, there's so much to unpack in that, still so much to experience and discover.
Thirdly, or it should've been firstly, I don't want my loved ones to ever suffer and die, although most likely they will. I will do everything in my power (through technology) to prevent that. When you hold you small child in your arms and you understand what an absolute treasure life is, I don't conceive willingly allowing that magic living being to die.
Death is for the majority of people extremely ugly. After 60, your body quickly deteriorates in horrible ways. Some people forget who they are, some spend the next decade immobilized and shitting their pants. Biological immortality would fix all that since it can only be achieved through rejuvenation. Very few lucky old people die at 90 in their sleep. Most suffer and start rotting (metaphorically) while still being alive.
Finally, I think this is an unhealthy attitude. Just like that of rich people that do extreme things because they are bored with life. If you found purpose in your life, something meaningful, helping your family, your community, your nation, anything greater than yourself, then you will always have something to do. Personally, there's so much I would do. I have innovative technologies in my head that I've never been able to materialize because I lack the money. I could help stray animals, people in my community and ensure a safe and prosperous future for my family. I could create a space empire, if you want to think outside the box. Anything is possible, but you must imagine that thing and try to make it a reality.
