I was thinking, and I think it would be awesome to have buyable single-use objects (something like potions) with the following effects:
Sunblock - sim can stay in hot sun longer without sunburn
Suntan Oil - sim is more likely to tan in sun
Aloe Vera Gel - cures or reduces the duration of sunburn
Calamine Lotion - cures or reduces the duration of poision ivy
Insect Repellent - reduces sim's chance of being attacked by bees
I don't know if something like this is even possible. If anything like this already exists, can someone please point me in the right direction?
