I've been finding it useful to use an audio cd on conscious breathing
to help me keep an even breathing pace.
It's apparently sold out now but you can be notified when it's
available if you enjoy doing breath work. I've been resisting breath
work but think that it does relate to physical immortality, and that
my resistance is my resistance to feeling whole.
If interested, the link is
