What's the real ground reality for seniors in Sector 24C?

Honestly, after the kids moved out, this big house feels too much. We're looking at a smaller 2BHK in Sector 24C, Chandigarh. Hospital proximity is key for us. How are the medical facilities there, like emergency care? Aur kya parks hain achhe se walk karne ke liye? Want something manageable, you know.
