Fitness joy/need

[Wulfik]

I came up with this idea for in-game content ( possible mod but oh boy ):

There might be added need for "fitness". If so it will be separate from joy or it will fill joy need instead. ( Based on how you think it would be best in-game )
There will be different types of fitness activities such as running/jump rope, punching bag, yoga, heavy lifting.
You would have to designate area for fitness, GYM, which would be filled with needed items such as punching bag, tread mill etc.

Your pawns exercising will give them boost for LONG period of time. For example if your pawn goes running either outside in some designated area or on a treadmill in nice gym, they will get health boost for example movement speed 1% and immunity speed 1% as they are exercising. After they repeatedly go to the gym and they run, this bonus could increase lets say up to 10% boost that will be ever present and will only decay if pawn gets sick ( which could decrease the bonus rapidly ) or if the pawn has so much work that he has no time for exercise. Just like getting good bonuses, they could get different effects such as muscle fever, tennis elbow, sprained ankle ( with negative side effects such as pain, slower movement speed, worse manipulation etc. ) These exercise activities could take a bit more time than normal joy activities hence the new need bar idea.

Also pawns will focus on different activities based on their skills:
Melee character - Punching bag, heavy lifting,... ( providing relevant boost for their combat )
Shooting character - Shooting range ( just joy object ), running,... ( providing relevant boost for their combat )
Medic, hauler, cleaner, research, cook, grower, socializer - yoga, running,group exercize... ( providing relevant boost for their life in colony )

You could also add in SPA with would be pure joy activity, that could help with healing different effects such as bad back or so and pawns could socialize. Massage table might be good idea too, swimming pools, etc.
You could end up with new rooms, new items, more detailed characters, new side effects, new problems and most importantly new possibilities.

What do you guys and girls think ? Am I too big of a dreamer ? Is this boring or too overpowered ? How would you change it or what would you like or deleted from these things ?
