Just my two cents:
I tend to disagree. It's almost like the traditional situation of the person who wins the lottery and then says they will work because otherwise they will sit home bored.
The only reason why you would be bored is because you are not seeking new interests. There is a tremendous amount of things that you are not doing, simply because you are not sure you like them as you never tried them.
I know without a doubt that I will die without doing one fraction of the things I wanted to do, and without going to many places I wanted to go. Life is just not long enough to accomplish everything.
Also, the amount of things that there are to do, are not static. There are hobbies and other things to do, that didn't exist 50 or 100 years ago, and so even if you are now 1 million years old, and have done everything possible on your bucket list, changes are there are now thousands of new things waiting for you.
There is nothing beautiful about being mortal, this is just yet another thing we tell ourselves in order to make our current condition more palatable.
