Summer Science Internships Age Restriction??

Hi guys! I’m a rising senior and I’m currently looking for summer science internships. I realized that I passed a lot of internships that have applications due mid January or earlier :// but I hope to find more lol. So I do know that another really good option is to take initiative and email many professors, but I was hoping to also apply to some good internship programs or summer programs that are under $5000 in cost, or possible have stipends :D. Unfortunately, it seems like programs such as the Arthritis Foundation or NIH SIP have age requirements that I can’t meet because I don’t turn 17 until August ;-;. Are there any other good programs that you guys recommend that are better than emailing professors and getting an internship, like SIMR? Thanks so much in advance :))
