I use rollers during the winter. I can leave my bike set up and if there's a nice day it's easy to ride outside. I'm not strong enough to spin out in the larger gears so I still get a good workout and it helps my technique. Mine are set up between the wall and the end of a fooseball table a door would be better but I don't have to do much to get ready and go riding. I watch Spinervals and other videos for entertainment.
50 is the new start of middle age!
