In order to wire for Home Security system using EtherCAT,

I was diving under floor yesterday.

I has tried it afternoon after temperature became high, and entered from the door of the floor storage, however it annoyed me very much.

It was tremendous fear to put my body into the narrow space, that height was just 40cm, and to do slow method of progression.

Of course, it was perfect dark under the floor and I was fear that what I should do if I was stuck.

When I thought "if an earthquake happen", I needed a considerable courage.

"If I don't do it, I cannot write the next colum of EtherCAT"

The thought made me to face difficulties resolutely, with slow method of progression.

Among them, I noticed that it was better to roll the body rather than tp creep forward, so I was rolling with the cold concrete flop.

I think that I couldn't carry out this work, unless I have been on diet.

Apparently, "in order to roll in under the floor", it seems I had a weight loss. w
