Tickling

I got a cactus, namely Cereus peruvianus, which I referred in a previous ently. "Fight against electromagnetic wave", says the description. It is said that the cactus eats electromagnetic wave from electronics. I put it in front of the monitor on my desk.
The producer termed cactuses "tickling", which sounds like both "pinprick" and "funny" in Japanese. It says that cactuses exert "tickling power" and are versatile as a panacea.

In addition, I set a Weeping Fig tree, a popular house plant, near my desk.
Because the tree is a tropical plant sensitive to cold, I worry about whether it can survive winter in Niigata.
