Workout every 2 weeks…. not twice a week !
 Tried some new problems.
 Middle line in D's collection 2 is simple but yet to be solved, though it's just V3/4.
 So is the left one on B wall. A bit narrow. 
 Yesterday I got to try Ganban-yoku; a popular style of  hot stone spa in Japan. 
 Lying on a hot floor in a prone or spine position then sweating up a storm,
 your metabolism is suspected to be strongly activated.
 Anyway, we have to freshen up now and then.
 Otherwise our productivity improvement offers little hope.
