- standing desk; standing burns twice more calories than sitting; I went with Ikea's Trotten model for 220€ (its cheaper but requires a lot of manual hand rotation to change the height and it forced me to stand up longer; it was hard for me to stand and work and because I don't have a simple button to lower the desk, it forced me stand up longer)

- tennis ball to massage my back by leaning with it on the wall

- laptop stand, external keyboard and external trackpad; for better posture during standing and sitting; trackpad is more comfortable for me than mouse)

- vitamin D supplements for the winter

- smartwatch or smart band to keep basic track of sleep and fitness; I went with Xiaomi Mi Band 6

- smart weight to keep track of my weight and set goals; I went with Mi Body Composition Scale
