All those gorgeous pictures of exploring inner space...it is so inviting...and looks so easy.
I got sucked in back in 1954...and have been diving off and on ever since. I got certified in 1965 and multiple times since. Just as I wouldn't go into outer space without adequate preparation, I don't go into inner space unprepared either.
In 1997 I discovered a heart defect and now have a pacemaker in my left shoulder. So now I check with my cardiologist and my dive master before pursuing one of my favorite pastimes. Yes, I can still dive if I use my head.
There's nothing quite like diving...but be smart about it. Winning a lawsuit provides scant satisfaction for someone who can never dive again, maybe never walk again, or maybe never even live again.
