To be honest, with #longcovid & #severeasthma i am not really looking forward to new year’s eve. It will be a day where #pacing and taking rest will be extremely difficult, a crash is to be expected as my available points (cronocarecoach.com ) remain the same but the day is longer. #chronicillness

Important new research from the Netherlands: Skeletal muscle properties in long COVID and ME/CFS differ from those induced by bed rest www.medrxiv.org/content/10.1... #LongCovid #MEcfs

Abstract
Patients with long COVID and myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) suffer from a reduced exercise capacity, skeletal muscle abnormalities and post-exertional malaise (PEM), where symptoms worsen with cognitive or physical exertion. PEM often results in avoidance of physical activity, resulting in a lower aerobic fitness, which may contribute to skeletal muscle abnormalities. Here, we compared whole-body exercise responses and skeletal muscle adaptations after strict 60-day bed rest in healthy people with those in patients with long COVID and ME/CFS, and healthy age- and sex-matched controls. Bed rest altered the respiratory and cardiovascular responses to (sub)maximal exercise, while patients exhibited respiratory alterations only at submaximal exercise. Bed rest caused muscle atrophy, and the reduced oxidative phosphorylation related to reductions in maximal oxygen uptake. Patients with long COVID and ME/CFS did not have muscle atrophy, but had less capillaries and a more glycolytic fibers, none of which were associated with maximal oxygen uptake. While the whole-body aerobic capacity is similar following bed rest compared to patients, the skeletal muscle characteristics differed, suggesting that physical inactivity alone does not explain the lower exercise capacity in long COVID and ME/CFS

Living with a chronic illness is tough. Today 3 colleagues threw a retirement party. it was planned months ahead,it allowed me to pal around it and have enough room tomorrow to recover.And then the weather changed, triggering my asthma, so i had to cancel something i was looking forward to.

Have you heard about #mDNS? It's one of those protocols that go under the radar, but that can really wreak havoc on your network if you don't manage it. While mainly used for consumer stuff, expect to see it in your network. It uses link local multicast so gets flooded at L2.

The skeleton for halloween got delivered yesterday, unpacked it today and been bit goofing around with it with eva, placing it on the couch, scaring her by placing it on her deskchair (scared her a bit); she in turn placed it on our bed, so i moved it to her bed and tucked it in as if asleep..
