Palpatine is hundreds of years old, possibly even as old as Yoda.

Obi-Wan Force healed Luke after the Tusken Raiders killed him. Think about it. Why wouldn’t the Tusken Raiders kill Luke? Why would Ob-Wan sacrifice himself when he could have easily made it back to the ship? My explanation is that Obi-Wan gave Luke his lifeforce, meaning he would die instead. He strained himself to last until the Death Star, and when the time came, gave himself into the Force.
