They are all not killed working. Neither of them. Especially given their age, this is why tricks are used to enhance their activity level so people don't ask silly questions.
From a management point of view: You have to be careful that you don't have an over-exposure (no, no risk for Frodo there

).
In fairness you have to coordinate the events and make sure they are balanced (if I worked for Frodo I would explain him that only doing sport events is very risky).
Usually you have:
- a team doing research and planning the event in detail (is someone giving a speech, who is he meeting, timing, security, ....)
- planning of style and clothes
- briefing of person who goes there
- styling the person who goes there (my boss often stops somewhere and changes into a new shirt and trousers three minutes before he
arrives to look good in pictures - that needs to be arranged)
- trip to the event and from event
- time spent there doing the actual event
Sometimes we don't get media coverage even though it is a good event. Hard luck.
And things look better from the outside - I had to accompany my boss recently to a very important event with lovely food - but I was working there, so no time to nibble on the sandwiches plus I was so scared I would have something stuck in my teeth. So I had a drink and left a lot of gorgeous food behind. Hard luck
