i m 17, 5 5 , about 155. i play football and run track. i smoke weed occasionally but my friends who i smoke with are average height or pretty tall. also, my dad s 6 5. i eat pretty healthy. my dad said he was pretty short until the end of his junior year/ summer before senior year but i m already half way through my senior year. i m pretty strong, i max out at 225 but i don t lift heavy on the regular. i ve also noticed my knees crack a few times everyday. i get my 8 hours every night, so im wondering why i havent had a growth spurt yet?
