I spent half that time in Critical Care (much of that on a ventilator, a small amount sedated), and most of the rest in a specialist neuro-rehab unit. I would have died otherwise.
Fortunately it cost me nothing - Thank Bevan for the NHS - but if I were in the US I imagine I would be financially crippled!
According to https://nchstats.com/average-cost-of-hospital-stays-in-us/#google_vignette the average is $3.025 per night. 4 months = 120 days = $363,000 = €313.307,21
