A bacteriophage is a virus which infects
bacteria. In particular, the bacteriophage T4 is a virus which infects E.Coli,
a bacteria that has been used extensively for molecular biology research. The
bacteriophage T4 exemplifies the life cycle of viruses. It exists as an
inactive virion until one of its extended 'legs' comes into contact with the
surface of an E. Coli. Sensors on the ends of its 'legs' recognize binding
sites on the surface of the host's cell, and this triggers the bacteriophage
into action. The bacteriophage binds to the surface of the host, punctures the
cell with its injection tube, and then injects its own genetic blueprint. This
genetic information subverts the host cell's normal operation and sets the
cell's biosynthetic machinery to work creating replicas of the virus. These
newly created viruses escape from the cell and then float about dormant until
one happens to come into contact with a new host cell.

Executive Colouring Book.
Copyrighted 1961, here are some pages from the very wry, Executive Coloring Book. It celebrates the idea that Americans fought in the war for
freedom only to be forced to live in glass buildings and conform to the 'status
quo'.

Friday Noon
Well, off I go. Got my shopping done for cooking tomorrow and now I am embarking on a first: My fifth day in a row walking the seawall. I've walked at least eleven kilometres a day for a working week. I couldn't face another early morning walk, but Friday afternoons tend to be rather un-busy and I like that.

My New Ritual: Walking in the Morning

Then I went to lunch with friend, David. We went to the smoke shop and I bought all the paraphernalia to "smoke" oil. It is called dabbing and it is an awesome way for a non-drinker and person with lung disease to get high. I got a medical marijuana card and went to a marijuana dispensary (across the street if you don't mind). What a world!
