Some thoughts about being 70+ years old (the old "old age"), the new "senior" age.

1. Whether or not the universe is cooling down it turns out to be
smaller than was previously thought. The cosmic egg we came from
may be just one of many similar parallel universe eggs.
I am still very focused on my work and try to avoid distractions.
On my .

2. Some of my planned semi-retirement activities never materialized so I
figure I may as well continue working instead. As I get older there are
some memory problems so I have developed coping strategies, like leaving
notes to myself.

3. I try to keep up with the latest technology, both real and imagined.
And I try to keep an open mind and
welcome new experiences.

4. My goal is to avoid lens design mistakes and so far I have done very well
that way. Other areas of life have occasional slip-ups.
