I agree with the premise for a couple of reasons, the largest being that with a character being of that age in that timeframe they would tecnically be considered already in the later stages of their life since the average lifespan of people during that time was around 40-45 years. Secondly, and also somewhat of an issue imo, is the character skill level at the beginning of the game. The skill level of the character is lower than what you find on 18-19 year olds, let alone the older companions and with a background such as the one created for the character it seems like after learning the various skills the character then just spent the next several years letting them atrophy until the beginning of the game, which seems counterintuitive to me and not just a little silly. Reducing the character age would allow the character a more realistic start given the skill levels and would also allow for a more realistic start from a roleplaying/authentism perspective.
