Hundred millions people across America have experienced “deadly” snow storm. Temperature below zero Celsius degree during second week of February 2021.

Almost all southern states to brace more icy and frigid temperature than normal February each year, the states include:

- Texas

- Louisiana

- Mississippi

- Alabama.

Our city, Baton Rouge, temperature reached -8 C (18 F) degree. This is our first time experienced to face lower temperature in the Southern state.

The storm caused several problems in our neighborhood and city:

- power outage

- no water supply

- roads block

- grocery stores are closed

Fig 02- Ice on all branches of tree

Many our neighbors have no electricity more than 50 hours since Monday, 15 February 2021.

Fig 03- Branches fall down on the street.

No signs of light until Wednesday afternoon, 17 February 2021. We don’t know until when.

Few neighbors had to leave because it was too cold inside and they don’t have a fire place inside their houses.

Since our neighborhoods have different grids, we and several neighbors are lucky to have light and water supply during snow storms and until today.

How about with your cities? Have your cities snow storm?

We have at least 3 new dangerous variants of Sars Cov 2 viruses (Covid 19) so far:

- UK variant, identified as B.1.1.7

- South Africa variant, called as 20H/501Y.V2 or B.1.351

- Brazil variant, known as P.2

As reported by BBC News (February 9, 2021), the scary facts that South Africa halted the employing of UK’s AstraZeneca – Oxford vaccine, because the vaccine didn’t effective against new virus variant (20H/501Y.V2 or B.1.351).

I have posted about AstraZeneca – Oxford vaccine compared to other two American vaccines, Pfizer – Biontech and Moderna vaccines. Please find at:

Is AstraZeneca Covid 19 Vaccine Suitable for Poor Countries? - Virus 31

The good news that another American vaccine, Johnson & Johnson has “good” efficacy to contain South Africa variant with one shot only, after proved by clinical trials.

Effective rate of Johnson & Johnson single shot vaccine in 3 important places (regions):

- 72% in the USA.

- 66% in Latin America, include Brazil

- 57% in South Africa

Hence, a Johnson & Johnson single shot vaccine is “estimated” able to give protection against Covid 19 virus and its new variants.

Men’s fertility mainly relates to sperm accounts, sperm movement and semen quality (Mayo Clinic, 2021).

It is believed the male fertility is decreasing globally due to many causes, include:

- exposure to pesticides

- obesity

- smoking

- stress

- exposure to chemical substances

- certain infections and illness

- lifestyle factors

Then, the question: May Covid 19 Reduce Men’s Fertility?


Based on study published in the Journal Reproduction, then reported by CNN on January 29, 2021

One of corner in the city garden

People who infected by Sars Cov 2 virus (corona virus) may affect on their fertility.

Based on primary observation to groups of fertile men with and without corona virus infections, then, the result shows that virus lead to impair of:

- sperm quality

- semen quality

The more serious infections, the lower sperm quality, thus higher possibility to reduce men fertility.

Even this is early observations, the findings make researchers to concern.

Take care!!

From internet searches, the prices of Chocolate Covered Strawberries are very varies. No price below US$ 1 each.

The most common prices range from US$ 15 to US$ 25 per a half dozen (6 pieces). Quite expensive for me.

- a half dozen (6 pieces) for $12; and a dozen (12 pieces) for $24

- a half dozen (6 pieces) for $15 infused with alcohol; a dozen (12 pieces) for $30 infused with alcohol.

I wonder, why are Chocolate Covered Strawberries so expensive?

The reasons might relate to:

- public perception as a “luxury” goods.

- highly demand

- chocolate is shorten life, thus, must be removed from store shelves quicker.

Chocolates are good to keep them in the refrigerator, but it is no problem for 10 hours at room temperature.

In addition to strawberries, other fruits are suitable as well to be covered by chocolates.

As a cat owners, we experienced with our cats vomiting, but we may wonder: why do they vomiting frequently?

There are many issues relate to cat vomited, some of them are:

- eating a houseplant

- ingesting a toy piece

- hairball in the stomach

- allergy and sensitive to certain foods

It is said that vomit is normal for cat. However, it is not normal if cat changes their behavior and has vomited very often.

We may judge the level of “the seriousness” of vomit is based on its content and colors:

- yellow and foamy lead to hairballs

- thick yellow bile mean that there is serious health problems such as kidney and infection.

We should find medical help immediately, if our cats have frequently yellow vomits and shown the following behaviors:
