No regrets but particularly at your age, I would want a good exit strategy. Realistically, if you get 10yrs before physically having to give it up, you beat the odds by a good margin.
In terms of having to get home after trips an feeling worn down...It's a different mindset...if you are feeling worn out, SLOW DOWN...it's OK to have a down day or three. You don't have to be anywhere any time.
